MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a syntaxin-binding protein. The encoded protein appears to play a role in release of neurotransmitters via regulation of syntaxin, a transmembrane attachment protein receptor. Mutations in this gene have been associated with infantile epileptic encephalopathy-4. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2010]
PHENOTYPE: Mice homozygous for a null allele exhibit total loss of neurotransmitter secretion from synaptic vesicles throughout development and massive neuron apoptosis after initial synaptogenesis, leading to widespread neurodegeneration and complete neonatal lethality. [provided by MGI curators]
