Vesicle-associated membrane protein-associated protein B/C is a protein that in humans is encoded by the VAPB gene.[1][2]

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.[2] The VAPB gene is found on the 20th human chromosome.
