Web1 jan. 2014 · The inward rectifier potassium channels are part of a heterogeneous family of potassium channels named Kir m.n or KCNJ.x. This family can be categorized into four subclasses: transport channels (Kir1.n, Kir 4.n, Kir 5.n, Kir 7.n), regular Kir channels (Kir2.n), G protein-gated channels (Kir 3.n), and ATP-sensitive channels (Kir 6.n) (Hibino et ...
