Summary: This gene is a member of the synaptotagmin gene family and encodes a protein similar to other family members that mediate calcium-dependent regulation of membrane trafficking in synaptic transmission. Studies of the orthologous gene in rat have shown that the encoded protein selectively modulates spontaneous synaptic-vesicle exocytosis and may also be involved in regulating calcium independent secretion in nonneuronal cells. Alternative splicing results in multiple transcript variants. The gene has previously been referred to as synaptotagmin XI but has been renamed synaptotagmin XII to be standard with mouse and rat official nomenclature.[provided by RefSeq, Apr 2010]
Annotation information: Note: In 2002, the HUGO Gene Nomenclature Committee (HGNC) changed the official nomenclature of this locus to be standard with mouse and rat official nomenclature. Therefore, the gene previously known as "synaptotagmin XI" (SYT11, GeneID 23208) became "synaptotagmin XII" (SYT12) and "synaptotagmin XII" (SYT12, GeneID 91683) became "synaptotagmin XI" (SYT11).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
