Transmembrane signaling by plant receptor kinases (RKs) has long been thought to involve reciprocal trans-phosphorylation of their intracellular kinase domains. The fact that many of these are pseudokinase domains, however, suggests that additional mechanisms must govern RK signaling activation. Non-catalytic (pseudo)kinase signaling mechanisms have been described in metazoans, but information is scarce for plants. Recently, a non-catalytic function was reported for the leucine-rich repeat (LRR) ...[more]

Molecular mechanism of β-arrestin-2 pre-activation by phosphatidylinositol 4,5-bisphosphate

Project description:Arrestins are a protein family that regulate G protein-coupled receptor (GPCR) signaling, with four distinct members in mammals (arrestin 1–4). Phosphorylated residues of G protein-coupled receptors bind to the N-domain of arrestin, resulting in C-terminus release. This induces further allosteric conformational changes, such as polar core disruption, alteration of interdomain loops, and domain rotation, which transform arrestins into the receptor-activated state. It is widely accepted that arrestin activation occurs by conformational changes propagated from the N- to the C-domain. However, recent studies have revealed that binding of phosphatidylinositol 4,5-bisphosphate (PIP2) to the C-domain transforms arrestins into an active state. In this study, we aimed to elucidate the mechanisms underlying PIP2-induced arrestin activation. We compared the conformational changes of β-arrestin-2 upon binding of PIP2 or phosphorylated C-tail peptide of vasopressin receptor type 2 (V2Rpp) using hydrogen/deuterium exchange mass spectrometry (HDX-MS). Introducing point mutations on the potential routes of the allosteric conformational changes and analyzing these mutant constructs with HDX-MS revealed that PIP2-binding at the C-domain affects the back loop, which destabilizes the gate loop and β-strand XX to transform β-arrestin-2 into the pre-active state.

Molecular mechanism of muscarinic acetylcholine receptor M3 interaction with Gq

Project description:Muscarinic acetylcholine receptor M3 (M3) and its downstream effector Gq/11 are critical drug development targets given their involvement in numerous physiological processes and diseases. Although a cryo-electron microscopy study previously defined the structure of the M3-miniGq complex, the lack of information on the intracellular loop 3 (ICL3) of M3 and α-helical domain (AHD) of Gαq has made it difficult to comprehend the molecular mechanism of M3-Gq coupling fully. Here, we present the molecular mechanism underlying the dynamic interactions between the wild-type full-length M3 and heterotrimeric Gq using hydrogen-deuterium exchange mass spectrometry and NanoLuc Binary Technology-based cell systems. This study suggests potential binding interfaces between M3 and Gq in pre-assembled and fully active nucleotide-free complexes. In addition to well-known binding interfaces, we observed the interaction of long ICL3 with Gβγ. Furthermore, M3 ICL3 negatively affected M3-Gq coupling, and the Gαq AHD underwent unique conformational changes during M3-Gq coupling. Therefore, we propose a comprehensive molecular mechanism of M3-Gq coupling by analyzing previously well-defined binding interfaces and neglected regions, such as M3 ICL3 and the Gαq AHD.

HDX-MS Analysis of CD47 Conformational Dynamics

Project description:CD47 is the only 5-transmembrane (5-TM) spanning receptor of the immune system. Its extracellular domain (ECD) is a cell surface ‘marker of self’ that binds SIRPα and inhibits macrophage phagocytosis, and cancer immuno-therapy approaches in clinical trials are focused on blocking CD47/SIRPα interaction. Using hydrogen-deuterium exchange we show that CD47’s ECLR architecture, comprised of two extracellular loops and the SWF loop, creates a molecular environment stabilizing the ECD for presentation on the cell surface.

c-di-GMP-induced conformational dynamics of the c-di-GMP-binding protein A (CdbA) from Myxococcus xanthus

Project description:The second messenger c-di-GMP has important functions in response to changing environmental and cellular cues in bacteria. Here, we report the identification of CdbA, a DNA binding protein of the ribbon-helix-helix family in Myxococcus xanthus, and show that it binds c-di-GMP in vitro. CdbA is essential for viability and its depletion caused defects in chromosome organization and segregation resulting in a block in cell division. CdbA binds multiple sites across the M. xanthus genome with moderate sequence specificity; however, its depletion only caused minor changes in transcription. C-di-GMP binding and DNA binding by CdbA are mutually exclusive and substitutions in the CdbA interfaces important for c-di-GMP binding not only abolished c-di-GMP binding but also DNA binding and rendered the mutant proteins non-functional in vivo. Our data are consistent with a model whereby CdbA functions as a nucleoid associated protein to organize the M. xanthus chromosome and the function of CdbA is modulated by c-di-GMP, thus, for the first time, establishing a link between c-di-GMP and chromosome organization and segregation.

Structural and mechanistic insights into the CAND1-mediated SCF substrate receptor exchange

Project description:Modular SCF (SKP1-CUL1-Fbox) ubiquitin E3 ligases orchestrate multiple cellular pathways in eukaryotes. Their variable SKP1-Fbox substrate receptor (SR) modules enable regulated substrate recruitment and subsequent proteasomal degradation. CAND proteins are essential for the efficient and timely exchange of SRs. To gain structural understanding of the underlying molecular mechanism, we reconstituted a CAND1-driven exchange reaction of substrate-bound SCF alongside its co-E3 ligase DCNL1 and visualised it by cryo-EM. We describe high-resolution structural intermediates including a ternary CAND1-SCF complex, as well as conformational and compositional intermediates representing SR- or CAND1-dissociation. We describe in molecular detail how CAND1-induced conformational changes in CUL1/RBX1 provide an optimised DCNL1 binding site and reveal an unexpected dual role for DCNL1 in CAND1-SCF dynamics. Moreover, a partially dissociated CAND1-SCF conformation accommodates cullin neddylation, leading to CAND1 displacement. Our structural findings, together with functional biochemical assays help formulate a detailed model for CAND-SCF regulation.

Structural mechanism underlying primary and secondary coupling between GPCRs and the Gi/o family

Project description:G protein-coupled receptors (GPCRs) are the largest receptor superfamily that can propagate various extracellular stimulus into cells by coupling with heterotrimeric G proteins. G proteins are divided into four families, Gs, Gi/o, Gq/11 and G12/13, which are responsible for the transduction of discrete downstream signaling pathways. Interestingly, one receptor can couple to more than one G protein subtype with different coupling efficiency or kinetics; coupling with the highest efficiency and/or kinetics is known as ‘primary coupling’ whereas the one with lower efficiency and/or slower kinetics is known as ‘secondary coupling’. Due to its significance in human physiology, there has been a great effort to elucidate the precise mechanism of GPCR-G protein coupling, however, the complex nature of GPCR and G protein interaction raises more unanswered questions. Here, we utilized hydrogen/deuterium exchange mass spectrometry (HDX-MS) to understand the molecular mechanism underlying primary and secondary Gi/o coupling using muscarinic acetylcholine receptor type 2 (M2R) and β2-adrenergic receptor (β2AR) as the primary and secondary Gi/o-coupling receptors, respectively. Results showed the engagement of the distal C-terminus of Gi/o with the receptor differentiates primary and secondary Gi/o couplings. In addition, the interaction between the intracellular loop 2 (ICL2) of the receptor and Gi/o in primary Gi/o coupling is not as critical as in primary Gs coupling.

Interaction of human eIF5A and DHS K329A variant studied by HDX-MS

Project description:Hypusination is a unique post-translational modification of the eukaryotic translation factor 5A (eIF5A) that is essential for overcoming ribosome stalling at polyproline sequence stretches. The initial step of hypusination, the formation of deoxyhypusine, is catalyzed by deoxyhypusine synthase (DHS), however, the molecular details of the DHS-mediated reaction remained elusive. Recently, patient-derived variants of DHS and eIF5A have been linked to rare neurodevelopmental disorders. Here, we present the cryo-EM structure of the human eIF5A-DHS complex at 2.8Å resolution and a crystal structure of DHS trapped in the key reaction transition state. Furthermore, we show that disease-associated DHS variants influence the complex formation and hypusination efficiency. Hence, our work dissects the molecular details of the deoxyhypusine synthesis reaction and reveals how clinically-relevant mutations affect this crucial cellular process.

Architecture of human Rag GTPase heterodimers and their complex with mTORC1

Project description:The Rag GTPases recruit the master kinase mTORC1 to lysosomes to regulate cell growth and proliferation in response to amino acid availability. The nucleotide state of Rag heterodimers is critical for their association with mTORC1. Our cryo-EM structure of RagA/RagC in complex with mTORC1 shows the details of RagA/C binding to the RAPTOR subunit of mTORC1 and explains why only the RagAGTP/RagCGDP nucleotide state binds mTORC1. Previous kinetic studies suggested that GTP binding to one Rag locks the heterodimer to prevent GTP binding to the other. Our crystal structures and dynamics show the mechanism for this locking, and explain how oncogenic hotspot mutations disrupt this process. In contrast to allosteric activation by RHEB, Rag heterodimer binding does not change mTORC1 conformation and activates mTORC1 by targeting it to lysosomes.

Structural dynamics of the chicken TRPV4 N-terminal domain

Project description:Intrinsically disordered regions (IDRs) are essential for membrane receptor regulation but often remain unresolved in structural studies. TRPV4, a member of the TRP vanilloid channel family involved in thermo- and osmosensation, has a large N-terminal IDR of approximately 150 amino acids. With an integrated structural biology approach, we analyze the structural ensemble of the TRPV4 IDR and identify a network of regulatory elements that modulate channel activity in a hierarchical lipid-dependent manner through transient long-range interactions. A highly conserved autoinhibitory patch acts as a master regulator by competing with PIP2 binding to attenuate channel activity. Molecular dynamics simulations show that loss of the interaction between PIP2-binding site and the membrane reduces the force exerted by the IDR on the structured core of TRPV4. This work demonstrates that IDR structural dynamics are coupled to TRPV4 activity and highlights the importance of IDRs for TRP channel function and regulation.
