Scientific Background

Scientific Background
    • 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 (GIRK) 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 channel1,2.
