Anti-K2p12.1 antibodies are used in antigen-specific immunodetection in biological samples. The target K2p12.1 is a known alias name of the protein potassium two pore domain channel subfamily K member 12, encoded by the KCNK12 gene in humans. This 430-amino acid residue protein is a suspected potassium channel subunit. It is localized to the membrane of the cell and features glycosylated post-translational modifications.
