Anti-Kv6.4 antibodies enable researchers to detect and measure the Kv6.4 antigen in biological samples. This target is a reported synonym of the KCNG4 gene, which encodes potassium voltage-gated channel modifier subfamily G member 4. This protein is known to function in potassium ion transport and protein oligomerization, among other biological roles. The human version of Kv6.4 has a canonical amino acid length of 519 residues and a protein mass of 59 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Kv6.4 is a member of the Potassium channel protein family.
