Anti-K2p13.1 antibodies enable researchers to detect and measure the K2p13.1 antigen in biological samples. This target is a reported synonym of the KCNK13 gene, which encodes potassium two pore domain channel subfamily K member 13. This protein is known to function in potassium ion transport and the transport of ions, among other biological roles. The human version of K2p13.1 has a canonical amino acid length of 408 residues and a protein mass of 45.4 kilodaltons. It is reported to be localized in the membrane of cells. K2p13.1 is a member of the Two pore domain potassium channel (TC 1.A.1.8) protein family.
