Anti-KCNK3 antibodies are used in the immunodetection of the protein potassium two pore domain channel subfamily K member 3. In humans, the canonical protein has a reported length of 394 amino acid residues and a mass of 43.5 kDa. Its subcellular localization is in the cell membrane. It is reported to be widely expressed in adult. A member of the Two pore domain potassium channel (TC 1.A.1.8) protein family, KCNK3 is known to be involved with brain development and the cellular response to hypoxia. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include OAT1, PPH4, TASK, TASK-1, TASK1, TBAK1, potassium channel subfamily K member 3, and K2p3.1. KCNK3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of KCNK3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
