Double C2-like domain-containing protein alpha is a protein that in humans is encoded by the DOC2A gene.[5][6][7]

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.[7]

Interactions

DOC2A has been shown to interact with UNC13B[6][8] and UNC13A.[9]
