Anti-potassium inwardly rectifying channel subfamily J member 14 antibodies are used for the immunodetection of the protein encoded by the KCNJ14 gene. In humans, the canonical protein has a reported length of 436 amino acid residues and a mass of 47.8 kDa. Its subcellular localization is in the membrane. It is noted to be expressed preferentially in retina. A member of the Inward rectifier-type potassium channel (TC 1.A.2.1) protein family, it is known to be involved with the transport of ions. Other names for this target antigen include KIR2.4, ATP-sensitive inward rectifier potassium channel 14, inward rectifier K(+) channel Kir2.4, inwardly rectifying potassium channel KIR2.4, and IRK4. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species.
