Intrinsically disordered proteins are thought to undergo coupled binding and folding upon interaction with their folded partners. In this study, we investigate whether binding of the intrinsically disordered T cell receptor zeta cytoplasmic tail to the well-folded simian immunodeficiency virus Nef core domain is accompanied by a disorder-to-order transition. We show that zeta forms a 1:1 complex with Nef and remains unfolded in the complex. Thus, our findings oppose the generally accepted view o ...[more]

Project description:We have recently demonstrated that simian immunodeficiency virus (SIV) Nef binds to the zeta chain of the T-cell receptor (TCR), leading to its down-modulation from T-cell surfaces (I. Bell, C. Ashman, J. Maughan, E. Hooker, F. Cook, and T. A. Reinhart, J. Gen. Virol. 79:2717-2727, 1998). Using a panel of human as well as rhesus macaque TCR zeta cytoplasmic domain mutants, we have identified in this report two linear peptides in the cytoplasmic domain of TCR zeta which independently interact with SIV Nef. Each SIV Nef interaction domain was sufficient in the absence of the other for interaction with SIV Nef in a yeast two-hybrid assay. In parallel, we demonstrated that Nef down-modulation of CD8-TCR zeta fusion proteins containing full-length or truncated portions of the TCR zeta cytoplasmic domain occurs in transiently transfected 293T cells. Furthermore, using proteins expressed in Escherichia coli, a glutathione S-transferase-Nef fusion protein coprecipitated histidine-tagged portions of the TCR zeta cytoplasmic domain which contained SNID-1 or SNID-2. The peptides targeted by SIV Nef, YNELNL and YSEIGMKGERRR, are portions of the first and second of three immunoreceptor tyrosine-based activation motifs which are important in signal transduction, thymocyte development, and TCR biogenesis. These results demonstrate that SIV Nef binds to two distinct domains on TCR zeta in the absence of other T-cell-specific factors, and that interaction with either domain is sufficient to cause down-modulation of TCR zeta.

Project description:The tetherin/BST2/CD317 protein blocks the release of HIV-1 and other enveloped viruses by inducing tethering of nascent particles to infected cell surfaces. The HIV-1 Vpu protein antagonizes the antiviral activity of human but not monkey tetherins and many simian immunodeficiency viruses (SIVs) do not encode Vpu. Here, we show that the apparently "missing" antitetherin activity in SIVs has been acquired by several SIV Nef proteins. Specifically, SIV(MAC)/SIV(SMM), SIV(AGM), and SIV(BLU) Nef proteins can suppress tetherin activity. Notably, tetherin antagonism by SIV Nef proteins is species specific, is genetically separable from other Nef activities, and is most evident with simian rather than human tetherin proteins. Accordingly, a critical determinant of sensitivity to SIV(MAC) Nef in the tetherin cytoplasmic tail is variable in nonhuman primate tetherins and deleted in human tetherin, likely due to selective pressures imposed by viral antagonists, perhaps including Nef proteins.

Project description:The role of the simian immunodeficiency virus (SIV) nef gene in viral replication was investigated in several tissue culture systems. SIVmac1A11 is a molecularly cloned virus which replicates in both peripheral blood mononuclear cells (PBMC) and macrophages, although no disease is observed in infected rhesus macaques. In this report, we demonstrate that SIVmac1A11 contains a full open reading frame for nef which specifies a 37-kDa protein. To investigate the effects of nef on viral replication, a 70-bp deletion was introduced into the nef gene of SIVmac1A11. Analysis of infected cell extracts by immunoblotting revealed that both SIVmac1A11 and nef deletion virus SIVmac1A11 delta nef produced the same viral proteins, except that Nef was absent in the mutant virus. The deletion mutation did not affect viral replication in PBMC, in monocyte-derived and alveolar macrophages obtained from rhesus macaques, and in human cell lines HUT-78 and CEMx-174. In addition, SIVmac1A11 and SIVmac1A11 delta nef exhibited similar patterns of cytopathologic changes and ultrastructural appearances in infected cells. SIVmac1A11 and SIVmac1A11 delta nef did not infect human tumor macrophage cell line U937, GCT, THP-1, or HL-60 cells, although virus was produced after these cells were transfected with either wild-type or nef mutant viral DNA. Similar levels of virus were recovered from U937 and THP-1 cells transfected with mutant and parental proviral DNAs. In transient expression assays in a T-cell line and a macrophage line, the nef protein of SIVmac1A11 did not significantly suppress or enhance expression of the chloramphenicol acetyltransferase reporter gene linked to the SIVmac long terminal repeat. Thus, abrogation of nef did not affect several in vitro properties of SIVmac1A11, including patterns of viral infection in rhesus PBMC, rhesus macrophages, or human T-cell lines.

Project description:Dynein light chain 8 (LC8) interacts with intrinsically disordered proteins (IDPs) and influences a wide range of biological processes. It is becoming apparent that among the numerous IDPs that interact with LC8, many contain multiple LC8-binding sites. Although it is established that LC8 forms parallel IDP duplexes with some partners, such as nucleoporin Nup159 and dynein intermediate chain, the molecular details of these interactions and LC8's interactions with other diverse partners remain largely uncharacterized. LC8 dimers could bind in either a paired "in-register" or a heterogeneous off-register manner to any of the available sites on a multivalent partner. Here, using NMR chemical shift perturbation, analytical ultracentrifugation, and native electrospray ionization MS, we show that LC8 forms a predominantly in-register complex when bound to an IDP domain of the multivalent regulatory protein ASCIZ. Using saturation transfer difference NMR, we demonstrate that at substoichiometric LC8 concentrations, the IDP domain preferentially binds to one of the three LC8 recognition motifs. Further, the differential dynamic behavior for the three sites and the size of the fully bound complex confirmed an in-register complex. Dynamics measurements also revealed that coupling between sites depends on the linker length separating these sites. These results identify linker length and motif specificity as drivers of in-register binding in the multivalent LC8-IDP complex assembly and the degree of compositional and conformational heterogeneity as a promising emerging mechanism for tuning of binding and regulation.

Project description:Amphiphilic molecules and their self-assembled structures have long been the target of extensive research due to their potential applications in fields ranging from materials design to biomedical and cosmetic applications. Increasing demands for functional complexity have been met with challenges in biochemical engineering, driving researchers to innovate in the design of new amphiphiles. An emerging class of molecules, namely, peptide amphiphiles, combines key advantages and circumvents some of the disadvantages of conventional phospholipids and block copolymers. Herein, we present new peptide amphiphiles composed of an intrinsically disordered peptide conjugated to two variants of hydrophobic dendritic domains. These molecules, termed intrinsically disordered peptide amphiphiles (IDPA), exhibit a sharp pH-induced micellar phase-transition from low-dispersity spheres to extremely elongated worm-like micelles. We present an experimental characterization of the transition and propose a theoretical model to describe the pH-response. We also present the potential of the shape transition to serve as a mechanism for the design of a cargo hold-and-release application. Such amphiphilic systems demonstrate the power of tailoring the interactions between disordered peptides for various stimuli-responsive biomedical applications.

Project description:Natively unfolded or intrinsically disordered proteins (IDPs) are under intense scrutiny due to their involvement in both normal biological functions and abnormal protein misfolding disorders. Polypeptide chain collapse of amyloidogenic IDPs is believed to play a key role in protein misfolding, oligomerization, and aggregation leading to amyloid fibril formation, which is implicated in a number of human diseases. In this work, we used bovine ?-casein, which serves as an archetypal model protein for amyloidogenic IDPs. Using a variety of biophysical tools involving both prediction and spectroscopic techniques, we first established that monomeric ?-casein adopts a collapsed premolten-globule-like conformational ensemble under physiological conditions. Our time-resolved fluorescence and light-scattering data indicate a change in the mean hydrodynamic radius from ?4.6 nm to ?1.9 nm upon chain collapse. We then took the advantage of two cysteines separated by 77 amino-acid residues and covalently labeled them using thiol-reactive pyrene maleimide. This dual-labeled protein demonstrated a strong excimer formation upon renaturation from urea- and acid-denatured states under both equilibrium and kinetic conditions, providing compelling evidence of polypeptide chain collapse under physiological conditions. The implication of the IDP chain collapse in protein aggregation and amyloid formation is also discussed.

Project description:The nef gene of the human and simian immunodeficiency viruses (HIV and SIV) is dispensable for viral replication in T-cell lines; however, it is essential for high virus loads and progression to simian AIDS (SAIDS) in SIV-infected adult rhesus macaques. Nef proteins from HIV type 1 (HIV-1), HIV-2, and SIV contain a proline-Xaa-Xaa-proline (PxxP) motif. The region of Nef with this motif is similar to the Src homology region 3 (SH3) ligand domain found in many cell signaling proteins. In virus-infected lymphoid cells, Nef interacts with a cellular serine/threonine kinase, designated Nef-associated kinase (NAK). In this study, analysis of viral clones containing point mutations in the nef gene of the pathogenic clone SIVmac239 revealed that several strictly conserved residues in the PxxP region were essential for Nef-NAK interaction. The results of this analysis of Nef mutations in in vitro kinase assays indicated that the PxxP region in SIV Nef was strikingly similar to the consensus sequence for SH3 ligand domains possessing the minus orientation. To test the significance of the PxxP motif of Nef for viral pathogenesis, each proline was mutated to an alanine to produce the viral clone SIVmac239-P104A/P107A. This clone, expressing Nef that does not associate with NAK, was inoculated into seven juvenile rhesus macaques. In vitro kinase assays were performed on virus recovered from each animal; the ability of Nef to associate with NAK was restored in five of these animals as early as 8 weeks after infection. Analysis of nef genes from these viruses revealed patterns of genotypic reversion in the mutated PxxP motif. These revertant genotypes, which included a second-site suppressor mutation, restored the ability of Nef to interact with NAK. Additionally, the proportion of revertant viruses increased progressively during the course of infection in these animals, and two of these animals developed fatal SAIDS. Taken together, these results demonstrated that in vivo selection for the ability of SIV Nef to associate with NAK was correlated with the induction of SAIDS. Accordingly, these studies implicate a role for the conserved SH3 ligand domain for Nef function in virally induced immunodeficiency.

Project description:Intrinsically disordered protein regions are widely distributed in the cytoplasmic domains of many transmembrane receptors. The cytoplasmic domain of a disintegrin and metalloprotease (ADAM)10, a transmembrane metalloprotease mediating ectodomain shedding of diverse membrane proteins, was recently suggested to mediate the homodimerization of ADAM10. Here we show that a recombinant cytoplasmic domain of ADAM10 (A10Cp) is unstructured as judged by its susceptibility to limited trypsin digestion and its circular dichroism spectrum. In comparison, recombinant transmembrane-cytoplasmic domain of ADAM10 (A10TmCp) reconstituted in dodecylphosphocholine (DPC) micelles exhibits much greater resistance to trypsin digestion, with its cytoplasmic domain taking on a significant ordered structure. FRET analysis demonstrates that, although A10Cp remains monomeric, A10TmCp forms a tight homodimer (K(d) ? 7 nM) in DPC micelles. Phospholipid-conjugated A10Cp dose-dependently inhibits formation of A10TmCp homodimer, whereas A10Cp achieves only limited inhibition. Placing the transmembrane and cytoplasmic domains of ADAM10, but not the transmembrane domain alone, in their native orientation in the inner membrane of Escherichia coli produces specific and strong dimerization signal in the AraC-based transcriptional reporter assay. A chimeric construct containing the otherwise monomeric transmembrane domain of L-selectin and the cytoplasmic domain of ADAM10 produces a similar dimerization signal. Overall, these results demonstrate that a transmembrane domain imparts a stable structure to the adjacent and intrinsically disordered cytoplasmic domain of ADAM10 to form a homodimer in the membrane. This finding advances our understanding of the regulatory mechanism of ADAMs and has general implications for membrane-protein interactions in the process of transmembrane signaling.

Project description:We show here that chicken gizzard caldesmon (CaD) and its C-terminal domain (residues 636-771, CaD136) are intrinsically disordered proteins. The computational and experimental analyses of the wild type CaD136 and series of its single tryptophan mutants (W674A, W707A, and W737A) and a double tryptophan mutant (W674A/W707A) suggested that although the interaction of CaD136 with calmodulin (CaM) can be driven by the non-specific electrostatic attraction between these oppositely charged molecules, the specificity of CaD136-CaM binding is likely to be determined by the specific packing of important CaD136 tryptophan residues at the CaD136-CaM interface. It is suggested that this interaction can be described as the "buttons on a charged string" model, where the electrostatic attraction between the intrinsically disordered CaD136 and the CaM is solidified in a "snapping buttons" manner by specific packing of the CaD136 "pliable buttons" (which are the short segments of fluctuating local structure condensed around the tryptophan residues) at the CaD136-CaM interface. Our data also show that all three "buttons" are important for binding, since mutation of any of the tryptophans affects CaD136-CaM binding and since CaD136 remains CaM-buttoned even when two of the three tryptophans are mutated to alanines.

Project description:Experimental evidence from the simian immunodeficiency virus (SIV) model of AIDS has shown that the nef gene is critical in the pathogenesis of AIDS. Consequently, nef is of considerable interest in both antiviral drug and vaccine development. Preliminary findings in two rhesus macaques indicated that a deletion of only 12 bp found in the overlapping nef/3' long terminal repeat (LTR) region (9501 to 9512) of the SIVmacC8 molecular clone was associated with reduced virus isolation frequency. We show that this deletion can be repaired in vivo by a sequence duplication event and that sequence evolution continues until the predicted amino acid sequence of the repair is virtually indistinguishable from that of the virulent wild type. These changes occurred concomitantly with reversion to virulence, evidenced by a high virus isolation frequency and load, decline in anti-p27 antibody, substantial reduction in the CD4/CD8 ratio, and development of opportunistic infections associated with AIDS. These findings clearly illustrate the capacity for repair of small attenuating deletions in primate lentiviruses and also strongly suggest that the region from 9501 to 9512 in the SIV nef/3' LTR region is of biological relevance. In addition, the ability of attenuated virus to revert to virulence raises fundamental questions regarding the nature of superinfection immunity.
