MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous mutant mice exhibited enhanced motor coordination during inverted screen testing. Mice homozygous for another knock-out allele exhibit hypotonia, impaired coordination in older mice and mild tremors. [provided by MGI curators]
