G protein-activated inward rectifier potassium channel 4 is a protein that in humans is encoded by the KCNJ5 gene and is a type of G protein-gated ion channel.Potassium channels are present in most mammalian cells where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel.
