Anti-TPCN2 antibodies are used in the immunodetection of the protein two pore segment channel 2. In humans, the canonical protein has a reported length of 752 amino acid residues and a mass of 85.2 kDa. Its subcellular localization is in the lysosomes. It is widely expressed across many tissue types. A member of the Calcium channel alpha-1 subunit (TC 1.A.1.11) protein family, TPCN2 is known to be involved with the regulation of intracellular calcium. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include two pore calcium channel protein 2, voltage-dependent calcium channel protein TPC2, and two pore channel protein 2. TPCN2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of TPCN2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
