背景 | Kir3.4 is a member of the G-protein regulated inward-rectifier K+ (GIRK) channel subfamily which is part of an inward-rectifier K+ channel superfamily. The GIRK subfamily comprises four members in mammals (Kir3.1- Kir3.4) that present the common topology of the inward-rectifier superfamily: two transmembrane domains flanking a highly conserved pore region with the N and C-terminus located intracellularly. Kir3.4 and the other Kir3 family subunits can be activated by neurotransmitters and other factors via the activation of G-protein coupled receptors. Binding of the corresponding ligand to the G-protein receptor induces the dissociation of G α-GTP from the Gβγ dimer. The latter directly binds to Kir3 and activates the channel. Kir3.4 expression is largely confined to the heart, where it co-assembles with Kir3.1 to form the prototypical muscarinic-gated K+ channel KACh. Indeed, knockout mice for Kir3.4 showed impaired heart rate following vagal nerve stimulation. A peptide toxin originating from the Apis mellifera bee venom, Tertiapin (#STT-250) was shown to be a potent blocker of Kir3.4 containing channels (8.6 nM for the Kir3.1/3.4 combination).4 |
