Anti-Kv12.2 antibodies enable researchers to detect and measure the Kv12.2 antigen in biological samples. This target is a reported synonym of the KCNH3 gene, which encodes potassium voltage-gated channel subfamily H member 3. This protein is known to function in potassium ion transport and the transport of ions, among other biological roles. The human version of Kv12.2 has a canonical amino acid length of 1083 residues and a protein mass of 117.1 kilodaltons. It is reported to be localized in the membrane of cells. Other names for this target antigen include BEC1, ELK2, and Kv12.2.
