Anti-KCNJ5 antibodies are used in the immunodetection of the protein potassium inwardly rectifying channel subfamily J member 5. In humans, the canonical protein has a reported length of 419 amino acid residues and a mass of 47.7 kDa. Its subcellular localization is in the membrane. It is notably widely expressed in many tissue types. A member of the Inward rectifier-type potassium channel (TC 1.A.2.1) protein family, KCNJ5 is known to be involved with the transport of ions. The KCNJ5 gene has been associated with the disease, Long QT syndrome. Synonyms for this target antigen include GIRK4, KATP1, KIR3.4, LQT13, G protein-activated inward rectifier potassium channel 4, and CIR. KCNJ5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of KCNJ5 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
