Rabbit anti-Human VAPA Polyclonal Antibody

Uniprot Id

Q9P0L0

Target Species

Human

Target Name

VAPA

Target Full Name

Vesicle-associated membrane protein-associated protein A

Target Function

Binds to OSBPL3, which mediates recruitment of VAPA to plasma membrane sites. The ORP3-VAPA complex stimulates RRAS signaling which in turn attenuates integrin beta-1 (ITGB1) activation at the cell surface. With OSBPL3, may regulate ER morphology. May play a role in vesicle trafficking.

Target Subcellular Location

Endoplasmic reticulum membrane; Single-pass type IV membrane protein. Cell membrane; Single-pass type IV membrane protein. Cell junction, tight junction. Nucleus membrane.

Target Protein Families

VAMP-associated protein (VAP) (TC 9.B.17) family

Target Tissue Specificity

Ubiquitous.

Target Synonyms

33 kDa Vamp-associated protein; hVAP 33; MGC3745; OTTHUMP00000162362; OTTHUMP00000162363; VAMP (vesicle-associated membrane protein) associated protein A, 33kDa; VAMP A; VAMP associated protein A; VAMP-A; VAMP-associated protein A; VAP 33; VAP A; VAP-33; VAP-A; VAP33; Vapa; VAPA_HUMAN; Vesicle associated membrane protein associated protein A; Vesicle-associated membrane protein-associated protein A

Target Background

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.
