Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). 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.[1][2]

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. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. It may associate with other G-protein-activated potassium channel subunits to form a heterotetrameric pore-forming complex.[2]

Mutations in KCNJ5/Kir3.4 cause Andersen-Tawil syndrome .[3]

Interactions

KCNJ5 has been shown to interact with KCNJ3.[4][5]
