Previous GeneCards Identifiers for DOC2A Gene
There are at least two protein isoforms of the Double C2 protein, namely alpha (DOC2A) and beta (DOC2B), which contain two C2-like domains. DOC2A and DOC2B are encoded by different genes; these genes are at times confused with the unrelated DAB2 gene which was initially named DOC-2. DOC2A is mainly expressed in brain and is suggested to be involved in Ca(2+)-dependent neurotransmitter release. Alternative splicing results in multiple transcript variants.

GeneCards Summary for DOC2A Gene
DOC2A (Double C2 Domain Alpha) is a Protein Coding gene. GO annotations related to this gene include calcium ion binding and syntaxin binding. An important paralog of this gene is SYTL3.
UniProtKB/Swiss-Prot for DOC2A Gene
Calcium sensor which most probably regulates fusion of vesicles with membranes. Binds calcium and phospholipids. May be involved in calcium dependent neurotransmitter release through the interaction with UNC13A. May be involved in calcium-dependent spontaneous release of neurotransmitter in absence of action potentials in neuronal cells. Regulates Ca(2+)-dependent secretory lysosome exocytosis in mast cells.
