VapA
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.

Interaction
Homodimer, and heterodimer with VAPB (PubMed:11511104). Interacts with VAMP1, VAMP2, STX1A, BET1, SEC22C and with the C-terminal domain of OCLN (PubMed:11511104, PubMed:9657962, PubMed:10523508). Interacts with OSBPL1A (By similarity). Interacts (via MSP domain) with ZFYVE27; may retain ZFYVE27 in the endoplasmic reticulum and regulate its function in cell projections formation (PubMed:19289470, PubMed:21976701).
