Anti-KCNQ1 antibodies are used in the immunodetection of the protein potassium voltage-gated channel subfamily Q member 1. In humans, the canonical protein has a reported length of 676 amino acid residues and a mass of 74.7 kDa. Its subcellular localization is in the cytoplasmic vesicles, ER, and cell membrane. Up to 2 different isoforms have been reported for this protein. It is found to be highly expressed in the heart, pancreas, prostate, kidney, small intestine and peripheral blood leukocytes. A member of the Potassium channel protein family, KCNQ1 is reported to be a potassium channel that plays an important role in a number of tissues, including heart, inner ear, stomach and colon. Synonyms for this target antigen include ATFB3, JLNS1, KCNA8, KCNA9, KVLQT1, Kv1.9, Kv7.1, and ATFB1. KCNQ1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 70 citations in the literature describe the use of KCNQ1 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
