Anti-KCNU1 antibodies are used in the immunodetection of the protein potassium calcium-activated channel subfamily U member 1. In humans, the canonical protein has a reported length of 1149 amino acid residues and a mass of 129.5 kDa. Its subcellular localization is in the cell membrane. It is reported to have testis-specific expression. A member of the Potassium channel protein family, KCNU1 is known to be involved with the transport of ions. Synonyms for this target antigen include Calcium-activated potassium channel subunit alpha-3, Calcium-activated potassium channel, subfamily M subunit alpha-3, Slowpoke homolog 3, and potassium channel subfamily U member 1. KCNU1 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. These KCNU1 antibodies are widely used in Western Blot experiments, among other applications.
