Anti-potassium channel, subfamily K, member 12 antibodies enable researchers to detect and measure the potassium channel, subfamily K, member 12 antigen in biological samples. This target is a reported synonym of the KCNK12 gene, which encodes potassium two pore domain channel subfamily K member 12. This protein is known to function in potassium ion transport and the transport of ions, among other biological roles. The human version of potassium channel, subfamily K, member 12 has a canonical amino acid length of 430 residues and a protein mass of 46.9 kilodaltons. It is reported to be localized in the membrane of cells. This target antigen may also be known as potassium channel, two pore domain subfamily K, member 12.
