Summary: Predicted to enable calcium ion binding activity and calcium-dependent phospholipid binding activity. Involved in regulation of calcium ion-dependent exocytosis. Acts upstream of or within spontaneous neurotransmitter secretion. Predicted to be located in cell junction; lysosome; and nuclear lumen. Is expressed in cerebral cortex. Orthologous to human DOC2A (double C2 domain alpha). [provided by Alliance of Genome Resources, Apr 2022]

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.
