Anti-DOC2B antibodies are used in the immunodetection of the protein double C2 domain beta. In humans, the canonical protein has a reported length of 412 amino acid residues and a mass of 45.9 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is reported to be widely expressed with highest levels in the brain and kidney. DOC2B is reported to be a calcium sensor, which positively regulates SNARE-dependent fusion of vesicles with membranes. Synonyms for this target antigen include double C2-like domain-containing protein beta, doc2-beta, double C2-like domains, beta, and DOC2BL. DOC2B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of DOC2B antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
