MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The synaptotagmins are integral membrane proteins of synaptic vesicles thought to serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis. Calcium binding to synaptotagmin-1 participates in triggering neurotransmitter release at the synapse (Fernandez-Chacon et al., 2001 [PubMed 11242035]).[supplied by OMIM, Jul 2010]
PHENOTYPE: Homozygous null mice do not suckle, show impaired synaptic transmission and Ca2+-evoked neurotransmitter release, and die by 48 hrs of life. Knock-in mice bearing a missense mutation show enhanced synaptic depression while those carrying a point mutationshow reduced synaptic release probability. [provided by MGI curators]
