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 one of three related synaptic vesicle proteins. The encoded protein may interact with synaptotagmin to enhance low frequency neurotransmission in quiescent neurons. [provided by RefSeq, Jun 2016]
PHENOTYPE: Homozygotes for targeted null mutations exhibit seizures, retarded growth, and reduced hippocampal (GABA)ergic neurotransmission. Many mutants die shortly after birth, and all are dead by three weeks of age. [provided by MGI curators]
