Gene

• Entrez ID: 8447
• Gene name: Double C2 domain beta
• Gene symbol: DOC2B
• Synonyms (NCBI Gene): DOC2BL
• Chromosome: 17
• Chromosome location: 17p13.3
• Summary: 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 wh

Protein

• UniProt ID: Q14184
• Protein name: Double C2-like domain-containing protein beta (Doc2-beta)
• Protein function: Calcium sensor which positively regulates SNARE-dependent fusion of vesicles with membranes. Binds phospholipids in a calcium-dependent manner and may act at the priming stage of fusion by modifying membrane curvature to stimulate fusion. Involv
