The protein encoded by VAPB is a type IV membrane protein found in plasma and intracellular vesicle membranes. Additionally we are shipping VAPB Proteins (13) and VAPB Kits (4) and many more products for this protein.

Effects of the combined absence of VAPA (show VAPA Antibodies) and VAPB in human cells were studied; cells lacking VAP (show F10 Antibodies) accumulate high levels of PI4P, actin comets, and trans-Golgi proteins on endosomes. Such defects are mimicked by downregulation of OSBP (show OSBP Antibodies), a VAP (show F10 Antibodies) interactor and PI4P transporter that participates in VAP (show F10 Antibodies)-dependent endoplasmic reticulum-endosomes tethers.
this is the first study to report Amyotrophic lateral sclerosis caused by a VAPB mutation in a Chinese population.
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.
Heterozygous P56S Vapb knock-in mice show mild age-dependent defects in motor behaviors as characteristic features of the disease. The homozygous P56S Vapb knock-in mice show more severe defects compared with heterozygous mice reflecting the dominant and dose-dependent effects of P56S mutation.
VAPB inhibited the degradation of DeltaF508-CFTR in the ER through interactions with the RMA1-Derlin-BAP31-VCP pathway.
Study characterizes the human VAPB-HCV NS5B interaction and reveals that NS5B C-linker is intrinsically disordered in solution but capable of binding the human VAPB-MSP (show MSMB Antibodies) domain which overlaps with those for binding HCV NS5A and human Eph (show EPHA1 Antibodies) receptors.
The VAPB and its interacting partners cooperatively regulate protein trafficking through the ERGIC by modulating PtdIns4P levels.
results suggest that the binding of vesicle-associated membrane protein-associated protein B(VAP-B) to Rab3 GTPase activating protein 1(RAB3GAP1 (show RAB3GAP1 Antibodies)) is implicated in the regulation of nuclear envelope formation through ER-Golgi intermediate compartment
P56S-VAPB was found to suppress adipocyte differentiation by promoting the activation of the ATF4 (show ATF4 Antibodies)-CHOP (show DDIT3 Antibodies) pathway
The repertoire of VAPB interactors is more diverse than previously anticipated and link VAPB to the function of ATPase (show DNAH8 Antibodies) complexes such as p97 (show EIF4G2 Antibodies)/FAF1 (show FAF1 Antibodies) and ASNA1 (show ASNA1 Antibodies)/transmembrane-domain recognition complex.
To identify pathological defects in animals expressing the P56S mutant VAPB protein at physiological levels in the appropriate tissues, we have generated Vapb knock-in mice
The disruption of the IRE1 (show ERN1 Antibodies)-XBP1 (show XBP1 Antibodies) pathway is a cause for the reduced myotube formation in P56S-VAPB-mutation expressing cells.
Vapb knock-out mice exhibit abnormal muscular triacylglycerol levels and FoxO (show FOXO3 Antibodies) target gene transcriptional responses to fasting and refeeding
Mice knocked-out for Vapb showed mild motor deficits after 18 months of age.
VapB positively regulates RANKL (show TNFSF11 Antibodies)-mediated osteoclastogenesis via PLCgamma2 (show PLCG2 Antibodies)-Ca(2 (show CA2 Antibodies)+)-NFAT (show NFATC1 Antibodies) signaling
Co-expression of mutant protein-associated protein B (show LEPREL2 Antibodies) (VAPB) enhances the transactive response DNA-binding protein (show HSF4 Antibodies)-43 (TDP-43 (show TARDBP Antibodies))-induced motor neuronal cell death while that of wild type-VAPB attenuates it.
Adeno (show ADORA2A Antibodies)-associated viral-mediated over-expression of both wild-type and mutated form of human VAPB selectively induces death of primary motor neurons, albeit with different kinetics.
However, VAPBP56S but not VAPBwt transgenic mice develop cytoplasmic TDP-43 (show TARDBP Antibodies) accumulations within spinal cord motor neurons that were first detected at 18 months of age.
The total loss of VAPB function in unfolded protein response, induced by one P56S mutant allele, may contribute to the development of P56SVAPB- induced amyotrophic lateral sclerosis.
The protein encoded by this gene is a type IV membrane protein found in plasma and intracellular vesicle membranes. The encoded protein is found as a homodimer and as a heterodimer with VAPA. This protein also can interact with VAMP1 and VAMP2 and may be involved in vesicle trafficking.
