MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the STXBP/unc-18/SEC1 family. The encoded protein is involved in intracellular trafficking, control of SNARE (soluble NSF attachment protein receptor) complex assembly, and the release of cytotoxic granules by natural killer cells. Mutations in this gene are associated with familial hemophagocytic lymphohistiocytosis. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jan 2013]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit complete preweaning lethality. Mice heterozygous for this allele exhibit decreased stimulated mucin secretion, release of histones in stimulated mast cells and decreased susceptibility to type I hypersensitivity reaction.
