Descrizione

Descrizione generale

G protein-activated inward rectifier potassium channel 4 (UniProt P48544; also known as Cardiac inward rectifier, CIR, Heart KATP channel, Inward rectifier K(+) channel Kir3.4, GIRK-4, IRK-4, KATP-1, Potassium channel, inwardly rectifying subfamily J member 5) is encoded by the KCNJ5 (also known as GIRK4, LQT13) gene (Gene ID 3762) in human. Inward rectifier K+ channels (Kirs) modulate cell membrane potential and are classified as K+ transport channels (Kir1.x, Kir4.x, Kir5.x, Kir7.x), classic Kir (Kir2.x), G-protein-gated Kirs (Kir2.x and Kir3.x), and ATP-sensitive Kirs (Kir6.x). Kirs mediate diverse physiological functions of both excitable and nonexcitable epithelial cells, such as cell adhesion-migration, volume regulation, apoptosis, and proliferation. While a large fraction of Kir3.4 (GIRK4; KCNJ5) subunits is processed to the cell membrane to form homomultimers, Kir3.4 subunits also assemble into heteromeric channels with Kir3.1 (GIRK1; KCNJ3) subunits in atrial myocytes or Kir3.2 (GIRK2; KCNJ6) in the cerebellum. Upon agonist activation of appropriate GPCRs, heteroterameric Kir3.4 channels are opened via interaction with subunits of the pertussis toxin-sensitive class (Gi/o) G-proteins, resulting in membrane hyperpolarization and/or reduced excitability. Whereas homotetrameric Kir3.4 channels can be activated by high intracellular Na+ independent of G-protein. Human Kir3.4 is a 419-amino acid multi-pass membrane (a.a. 87-111, 136-147, 164-185) protein that contains two small extraceullar regions (a.a. 112-135 and 155-163) and a pore-forming domain (a.a. 148-154), having both its N- and C-terminal ends exposed intracellularly (a.a. 1-86 and a.a. 186-419).
