Polymerase ?-interacting Protein 2: A Multifunctional Protein.

ABSTRACT: Polymerase ?-interacting protein 2 (Poldip2) is a multifunctional protein originally described as a binding partner of the p50 subunit of DNA polymerase ? and proliferating cell nuclear antigen. In addition to its role in DNA replication and damage repair, Poldip2 has been implicated in mitochondrial function, extracellular matrix regulation, cell cycle progression, focal adhesion turnover, and cell migration. However, Poldip2 functions are incompletely understood. In this review, we discuss recent literature on Poldip2 tissue distribution, subcellular localization, and function. We also address the putative function of Poldip2 in cardiovascular disease, neurodegenerative conditions and in renal pathophysiology.

Aminoacyl tRNA synthetase complex interacting multifunctional protein 1 simultaneously binds Glutamyl-Prolyl-tRNA synthetase and scaffold protein aminoacyl tRNA synthetase complex interacting multifunctional protein 3 of the multi-tRNA synthetase complex.

Project description:Higher eukaryotes have developed extensive compartmentalization of amino acid (aa) - tRNA coupling through the formation of a multi-synthetase complex (MSC) that is composed of eight aa-tRNA synthetases (ARS) and three scaffold proteins: aminoacyl tRNA synthetase complex interacting multifunctional proteins (AIMP1, 2 and 3). Lower eukaryotes have a much smaller complex while yeast MSC consists of only two ARS (MetRS and GluRS) and one ARS cofactor 1 protein, Arc1p (Simos et al., 1996), the homolog of the mammalian AIMP1. Arc1p is reported to form a tripartite complex with GluRS and MetRS through association of the N-terminus GST-like domains (GST-L) of the three proteins (Koehler et al., 2013). Mammalian AIMP1 has no GST-L domain corresponding to Arc1p N-terminus. Instead, AIMP3, another scaffold protein of 18 kDa composed entirely of a GST-L domain, interacts with Methionyl-tRNA synthetase (MARS) (Quevillon et al., 1999) and Glutamyl-Prolyl-tRNA Synthetase (EPRS) (Cho et al., 2015). Here we report two new interactions between MSC members: AIMP1 binds to EPRS and AIMP1 binds to AIMP3. Interestingly, the interaction between AIMP1 and AIMP3 complex makes it the functional equivalent of a single Arc1p polypeptide in yeast. This interaction is not mapped to AIMP1 N-terminal coiled-coil domain, but rather requires an intact tertiary structure of the entire protein. Since AIMP1 also interacts with AIMP2, all three proteins appear to compose a core docking structure for the eight ARS in the MSC complex.

PDIP46 (DNA polymerase ? interacting protein 46) is an activating factor for human DNA polymerase ?.

Project description:PDIP46 (SKAR, POLDIP3) was discovered through its interaction with the p50 subunit of human DNA polymerase ? (Pol ?). Its functions in DNA replication are unknown. PDIP46 associates with Pol ? in cell extracts both by immunochemical and protein separation methods, as well as by ChIP analyses. PDIP46 also interacts with PCNA via multiple copies of a novel PCNA binding motif, the APIMs (AlkB homologue-2 PCNA-Interacting Motif). Sites for both p50 and PCNA binding were mapped to the N-terminal region containing the APIMs. Functional assays for the effects of PDIP46 on Pol ? activity on singly primed ssM13 DNA templates revealed that it is a novel and potent activator of Pol ?. The effects of PDIP46 on Pol ? in primer extension, strand displacement and synthesis through simple hairpin structures reveal a mechanism where PDIP46 facilitates Pol ?4 synthesis through regions of secondary structure on complex templates. In addition, evidence was obtained that PDIP46 is also capable of exerting its effects by a direct interaction with Pol ?, independent of PCNA. Mutation of the Pol ? and PCNA binding region resulted in a loss of PDIP46 functions. These studies support the view that PDIP46 is a novel accessory protein for Pol ? that is involved in cellular DNA replication. This raises the possibility that altered expression of PDIP46 or its mutation may affect Pol ? functions in vivo, and thereby be a nexus for altered genomic stability.

Identification of PCNA-interacting protein motifs in human DNA polymerase ?.

Project description:DNA polymerase ? (Pol?) is a highly processive essential replicative DNA polymerase. In humans, the Pol? holoenzyme consists of p125, p50, p68 and p12 subunits and recently, we showed that the p12 subunit exists as a dimer. Extensive biochemical studies suggest that all the subunits of Pol? interact with the processivity factor proliferating cell nuclear antigen (PCNA) to carry out a pivotal role in genomic DNA replication. While PCNA-interacting protein motif (PIP) motifs in p68, p50 and p12 have been mapped, same in p125, the catalytic subunit of the holoenzyme, remains elusive. Therefore, in the present study by using multiple approaches we have conclusively mapped a non-canonical PIP motif from residues 999VGGLLAFA1008 in p125, which binds to the inter-domain-connecting loop (IDCL) of PCNA with high affinity. Collectively, including previous studies, we conclude that similar to Saccharomyces cerevisiae Pol?, each of the human Pol? subunits possesses motif to interact with PCNA and significantly contributes toward the processive nature of this replicative DNA polymerase.

Polymerase delta interacting protein 2 sustains vascular structure and function.

Project description:On the basis of previous evidence that polymerase delta interacting protein 2 (Poldip2) increases reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (Nox4) activity in vascular smooth muscle cells, we hypothesized that in vivo knockdown of Poldip2 would inhibit reactive oxygen species production and alter vascular function.Because homozygous Poldip2 deletion is lethal, Poldip2(+/-) mice were used. Poldip2 mRNA and protein levels were reduced by ?50% in Poldip2(+/-) aorta, with no change in p22phox, Nox1, Nox2, and Nox4 mRNAs. NADPH oxidase activity was also inhibited in Poldip2(+/-) tissue. Isolated aortas from Poldip2(+/-) mice demonstrated impaired phenylephrine and potassium chloride-induced contractions, increased stiffness, and reduced compliance associated with disruption of elastic lamellae and excessive extracellular matrix deposition. Collagen I secretion was elevated in cultured vascular smooth muscle cells from Poldip2(+/-) mice and restored by H2O2 supplementation, suggesting that this novel function of Poldip2 is mediated by reactive oxygen species. Furthermore, Poldip2(+/-) mice were protected against aortic dilatation in a model of experimental aneurysm, an effect consistent with increased collagen secretion.Poldip2 knockdown reduces H2O2 production in vivo, leading to increases in extracellular matrix, greater vascular stiffness, and impaired agonist-mediated contraction. Thus, unaltered expression of Poldip2 is necessary for vascular integrity and function.

Polymerase ?-interacting protein 2 promotes postischemic neovascularization of the mouse hindlimb.

Project description:Collateral vessel formation can functionally compensate for obstructive vascular lesions in patients with atherosclerosis. Neovascularization processes are triggered by fluid shear stress, hypoxia, growth factors, chemokines, proteases, and inflammation, as well as reactive oxygen species, in response to ischemia. Polymerase ?-interacting protein 2 (Poldip2) is a multifunctional protein that regulates focal adhesion turnover and vascular smooth muscle cell migration and modifies extracellular matrix composition. We, therefore, tested the hypothesis that loss of Poldip2 impairs collateral formation.The mouse hindlimb ischemia model has been used to understand mechanisms involved in postnatal blood vessel formation. Poldip2(+/-) mice were subjected to femoral artery excision, and functional and morphological analysis of blood vessel formation was performed after injury. Heterozygous deletion of Poldip2 decreased the blood flow recovery and spontaneous running activity at 21 days after injury. H2O2 production, as well as the activity of matrix metalloproteinases-2 and -9, was reduced in these animals compared with Poldip2(+/+) mice. Infiltration of macrophages in the peri-injury muscle was also decreased; however, macrophage phenotype was similar between genotypes. In addition, the formation of capillaries and arterioles was impaired, as was angiogenesis, in agreement with a decrease in proliferation observed in endothelial cells treated with small interfering RNA against Poldip2. Finally, regression of newly formed vessels and apoptosis was more pronounced in Poldip2(+/-) mice.Together, these results suggest that Poldip2 promotes ischemia-induced collateral vessel formation via multiple mechanisms that likely involve reactive oxygen species-dependent activation of matrix metalloproteinase activity, as well as enhanced vascular cell growth and survival.

Crystal structure of Escherichia coli Rnk, a new RNA polymerase-interacting protein.

Project description:Sequence-based searches identified a new family of genes in proteobacteria, named rnk, which shares high sequence similarity with the C-terminal domains of the Gre factors (GreA and GreB) and the Thermus/Deinococcus anti-Gre factor Gfh1. We solved the X-ray crystal structure of Escherichia coli regulator of nucleoside kinase (Rnk) at 1.9 A resolution using the anomalous signal from the native protein. The Rnk structure strikingly resembles those of E. coli GreA and GreB and Thermus Gfh1, all of which are RNA polymerase (RNAP) secondary channel effectors and have a C-terminal domain belonging to the FKBP fold. Rnk, however, has a much shorter N-terminal coiled coil. Rnk does not stimulate transcript cleavage in vitro, nor does it reduce the lifetime of the complex formed by RNAP on promoters. We show that Rnk competes with the Gre factors and DksA (another RNAP secondary channel effector) for binding to RNAP in vitro, and although we found that the concentration of Rnk in vivo was much lower than that of DksA, it was similar to that of GreB, consistent with a potential regulatory role for Rnk as an anti-Gre factor.

DNA polymerase ?-interacting protein 2 is a processivity factor for DNA polymerase ? during 8-oxo-7,8-dihydroguanine bypass.

Project description:The bypass of DNA lesions by the replication fork requires a switch between the replicative DNA polymerase (Pol) and a more specialized translesion synthesis (TLS) Pol to overcome the obstacle. DNA Pol ?-interacting protein 2 (PolDIP2) has been found to physically interact with Pol ?, Pol ?, and Rev1, suggesting a possible role of PolDIP2 in the TLS reaction. However, the consequences of PolDIP2 interaction on the properties of TLS Pols remain unknown. Here, we analyzed the effects of PolDIP2 on normal and TLS by five different human specialized Pols from three families: Pol ? (family B), Pol ? and Pol ? (family Y), and Pol ? and Pol ? (family X). Our results show that PolDIP2 also physically interacts with Pol ?, which is involved in the correct bypass of 8-oxo-7,8-dihydroguanine (8-oxo-G) lesions. This interaction increases both the processivity and catalytic efficiency of the error-free bypass of a 8-oxo-G lesion by both Pols ? and ?, but not by Pols ? or ?. Additionally, we provide evidence that PolDIP2 stimulates Pol ? without affecting its fidelity, facilitating the switch from Pol ? to Pol ? during 8-oxo-G TLS. PolDIP2 stimulates Pols ? and ? mediated bypass of other common DNA lesions, such as abasic sites and cyclobutane thymine dimers. Finally, PolDIP2 silencing increases cell sensitivity to oxidative stress and its effect is further potentiated in a Pol ? deficient background, suggesting that PolDIP2 is an important mediator for TLS.

CDC42-Interacting Protein 4 Gene Is Down Trans-Regulated by HBV DNA polymerase Trans Activated Protein 1.

Project description:BackgroundHepatitis B Virus (HBV) DNA polymerase transactivated protein 1 (HBVDNAPTP1) is a novel protein transactivated by HBV DNA polymerase, screened by suppression subtractive hybridization technique (GenBank accession no: AY450389). The biological function of HBVDNAPTP1 was investigated in this study.MethodsWe constructed a vector pcDNA3.1 (-)/myc-His A-HBVDNAPTP1 and used it to transfect acute monocytic leukemia cell line THP-1. HBVDNAPTP1 expression was detected by western blot analysis in the cells. A cDNA library of genes transactivated by HBVDNAPTP1 in THP-1 cells was made in pGEM-T Easy using suppression subtractive hybridization (SSH). The cDNAs were sequenced and analyzed with BLAST search against the sequences in GenBank.ResultsSome sequences, such as CIP4, might be involved in apoptosis development. mRNA and protein expression of CIP4 was identified by Real time RT-PCR and western blot in THP-1 cells. HBVDNAPTP1 could down-regulate the expression of CIP4 at both transcription and translation levels.ConclusionHBVDNAPTP1 may be involved in the positive regulation on the initiation of monocyte apoptosis. The result contribute to reveal the HBVDNAPTP1 biological functions and provide new evidences for further exploration of the regulatory mechanism of HBVDNAPTP1.

MicroRNA-95 promotes myogenic differentiation by down-regulation of aminoacyl-tRNA synthase complex-interacting multifunctional protein 2.

Project description:MicroRNA-95 (miR-95) is well known for its ability to promote the proliferation of a variety of cancer cells, but its function in skeletal muscle development has not been reported so far. Our laboratory has recently generated genetically engineered Meishan pigs containing a loss-of-function myostatin (MSTN) mutant (MSTN-/-). These MSTN-/- pigs grow and develop normally but show clear double muscle phenotype as observed in Belgian cattle. We observed that the expression of miR-95 was up-regulated in the longissimus dorsi from MSTN-/- Meishan pigs at day 65 during embryo development. In this study, we investigated the role of miR-95 in the myogenic differentiation using a murine myoblast cell line C2C12. Our results revealed that miR-95 may play a very important role in regulating the expression of myogenic differentiation marker genes myosin heavy chain (MHC) and myogenin. By use of bioinformatical analysis and luciferase reporter gene assay, aminoacyl-tRNA synthase complex-interacting multifunctional protein 2 (AIMP2) gene was identified as a miR-95 target gene involved in myogenic differentiation. Our results indicated that higher miR-95 expression level leads to lower level of AIMP2 protein expression. When the endogenous expression of AIMP2 is inhibited by siRNA, the expression levels of myogenic differentiation marker genes MHC and myogenin increased, implying that AIMP2 negatively regulates myogenic differentiation. Taken together, it is likely that miR-95 promotes myogenic differentiation in C2C12 myoblasts and may play a positive functional role in skeletal muscle development by down regulating the expression of AIMP2 at protein level.

Defining the microglia transcriptome in multifunctional protein-2 deficient mice

Project description:Purpose: We purified whole brain microglia of MFP2 knockout mice and control mice utilizing percoll gradient and FACS sorting, followed by microarray analysis to define the molecular changes in MFP2 knockout mice at the endstage of the disease. We compared the microglia transcriptome of Mfp2-/- microglia to that of SOD1-G93A microglia isolated from spinal cord to define the microglia signature associated with a non-neurodegenerative environment. Results and conclusions: Mfp2-/- microglia acquire an activation state characterized by activation of mammalian target of rapamycin (mTOR). In addition, activated microglia display reduced expression of genes that are normally highly expressed by surveillant microglia in steady-state conditions. The immunological profile of is heterogeneous and encompasses upregulation of both pro- and anti-inflammatory genes. In contrast to the neurodegeneration-specific microglia profile in SOD1-G93A mice, Mfp2-/- microglia do not induce genes associated with phagocytosis, lysosomal activation and neurotoxicity. 4 MFP2 knockout and 4 control samples were subjected to microarray analysis.
