Human VAMP (Vesicle-Associated Membrane Protein)-Associated Protein A, 33kDa (VAPA) interaction partners

  1. the component proteins of the machinery, OSBP, VAP, SAC1, and PITPNB, are all essential host factors for AiV replication. Importantly, the machinery is directly recruited to the RNA replication sites through previously unknown interactions of VAP/OSBP/SAC1 with the AiV proteins and with ACBD3.

  2. VAP-ACBD5-mediated contact between the endoplasmic reticulum and peroxisomes mediate organelle maintenance and lipid homeostasis.

  3. Effects of the combined absence of VAPA and VAPB in human cells were studied; cells lacking VAP accumulate high levels of PI4P, actin comets, and trans-Golgi proteins on endosomes. Such defects are mimicked by downregulation of OSBP, a VAP interactor and PI4P transporter that participates in VAP-dependent endoplasmic reticulum-endosomes tethers.

  4. Our work revealed that VAP-A/B knockdown impaired the processing and secretion of PAUF, which is one of the cargo proteins of carriers of the trans-Golgi network to the cell surface.

  5. The effects of sterol manipulation of HuH7 cells on complexes of established sterol-binding Oxysterol-binding protein related proteins with their endoplasmic reticulum receptor, VAMP-associated protein A (VAPA), were examined.

  6. phosphorylation of ORP3 controls its association with VAPA. Furthermore, ORP3-VAPA complexes stimulate R-Ras signaling.

  7. GPS2 is required for the association of viral NS5A with VAP-A and hepatitis C virus replication.

  8. STARD3 or STARD3NL and VAP form a novel molecular tether between late endosomes and the endoplasmic reticulum.

  9. phosphorylation of CERT at the FFAT motif-adjacent serine affects its affinity for VAP, which may regulate the inter-organelle trafficking of ceramide in response to the perturbation of cellular sphingomyelin and/or other sphingolipids

  10. Viperin inhibits hepatitis C virus replication by interfering with binding of NS5A to host protein VAP-33.

  11. Data show that the methylated VAPA-APCDD1 DNA in maternal plasma is predominantly derived from the fetus, and this novel fetal epigenetic marker in maternal plasma is useful for the noninvasive detection of fetal trisomy 18.

  12. three conserved prolines in VAPA and Scs2p confers less vulnerability to mutations equivalent to the amyotrophic lateral sclerosis causing mutation as compared with VAPB, which has only two conserved prolines.

  13. Electrostatic interaction between oxysterol-binding protein and VAMP-associated protein A revealed by NMR and mutagenesis studies.

  14. protein-protein interactions among the various HCV NS proteins and hVAP-33 are important for the formation of HCV replication complex

  15. Our results provide suggestive evidence of an association between SNPs in the 3'UTR of the VAPA gene and bipolar disorder.

  16. Data show that overexpression of VAPA and VAPB causes retention of ER membrane proteins by impeding lateral diffusion and their incorporation into transport vesicles.

  17. VAP-A is an important regulator both of the subcellular localization of protrudin and of its ability to stimulate neurite outgrowth.

  18. GLTP and VAP-A were shown to interact.

Protein Summary

The protein encoded by this gene is a type IV membrane protein. It is present in the plasma membrane and intracellular vesicles. It may also be associated with the cytoskeleton. This protein may function in vesicle trafficking, membrane fusion, protein complex assembly and cell motility. Alternative splicing occurs at this locus and two transcript variants encoding distinct isoforms have been identified.
