Anti-Kv7.4 antibodies enable researchers to detect and measure the Kv7.4 antigen in biological samples. This target is a reported synonym of the KCNQ4 gene, which encodes potassium voltage-gated channel subfamily Q member 4. This protein is known to function in potassium ion transport and the transport of ions, among other biological roles. The human version of Kv7.4 has a canonical amino acid length of 695 residues and a protein mass of 77.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include DFNA2, DFNA2A, and KV7.4.
