Background: KCNJ3, G protein-activated inward rectifier potassium channel 1,Kir3.1 (or G-protein regulated inward-rectifier K+ channel 1, GIRK1) is a member of the family of inward rectifying K+ channels. The family includes 15 members that are structurally and functionally different from the voltage-dependent K+ channels.The family's topology consists of two transmembrane domains that flank a single and highly conserved pore region with intracellular N- and C-termini. As is the case for the voltage-dependent K+ channels, the functional unit for the Kir channels is composed of four subunits that can assemble as either homo- or heterotetramers.Kir channels are characterized by a K+ efflux that is limited by depolarizing membrane potentials thus making them essential for controlling resting membrane potential and K+ homeostasis.Kir3.1 is a member of the Kir3.x subfamily that includes four members (Kir3.1- Kir3.4). The Kir3 family is characterized by the fact that the channels can be activated by neurotransmitters and other factors acting via the activation of G-protein coupled receptors. Binding of the corresponding ligand to the G-protein receptor induces the dissociation of Gα-GTP from the Gβγ dimer. The latter directly binds to Kir3 and activates the channel1,3.In the heart, Kir3.1 co-assembles with Kir3.4 to form the prototypical muscarinic-gated K+ channel KAch current, responsible for slowing the heart rate in response of parasympathetic stimulation2.In the brain, Kir3.1 co-assembles with Kir3.2 and mediates the inhibitory effects of many neurotransmitters including opioid, adrenergic, muscarinic, dopaminergic and γ-aminobutyric acid (GABA)1,3.A peptide toxin originating from the Apis mellifera bee venom, Tertiapin (#STT-250) was shown to be a potent blocker of Kir3.1 containing channels (8.6 nM for the Kir3.1/3.4 combination and 5.4 nM for the Kir3.1/3.2)4,5.
