FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene, a member of the SNAP25 gene family, encodes a protein involved in multiple membrane trafficking steps. Two other members of this gene family, SNAP23 and SNAP25, encode proteins that bind a syntaxin protein and mediate synaptic vesicle membrane docking and fusion to the plasma membrane. The protein encoded by this gene binds tightly to multiple syntaxins and is localized to intracellular membrane structures rather than to the plasma membrane. While the protein is mostly membrane-bound, a significant fraction of it is found free in the cytoplasm. Use of multiple polyadenylation sites has been noted for this gene.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit slightly reduced birth body size and a congenital ichtyotic phenotype associated with scaly and tight skin, hyperkeratosis, acanthosis, abnormalities in epidermal differentiation and autophagy, and increased endoplasmic reticulum stress.
