Molecular Target Synopsis - Kcnj8 (Q63664) - Overview

Protein


Kcnj8, ATP-sensitive inward rectifier potassium channel 8
UniProt Q63664

Also Known as IRK8_RAT, Kcnj8

This potassium channel is controlled by G proteins. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by external barium.
