Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables calcium ion binding activity; inositol 1,3,4,5 tetrakisphosphate binding activity; and phospholipid binding activity. Involved in calcium-dependent activation of synaptic vesicle fusion. Located in axon and plasma membrane. Is active in neuromuscular junction. Is expressed in several structures, including central nervous system; heart; integumental system; peripheral nervous system; and sensory organ. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome and congenital myasthenic syndrome 7. Orthologous to human SYT2 (synaptotagmin 2). PHENOTYPE: Mice homozygous for an ENU-induced allele are viable but sterile, weigh less and show ataxia and altered spontaneous and Ca2+-evoked neurotransmitter release. Mice homozygous for a null allele die at weaning showing growth arrest, motor dysfunction and impaired Ca2+-evoked neurotransmitter release. [provided by MGI curators] |
