Mitochondrial potassium channel located in the mitochondrial inner membrane . Together with ABCB8/MITOSUR, forms a protein complex localized in the mitochondria that mediates ATP-dependent potassium currents across the inner membrane (that is, mitoK(ATP) channel) . May contribute to the homeostatic control of cellular metabolism under stress conditions by regulating the mitochondrial matrix volume .
Subcellular locations: Mitochondrion inner membrane
Subcellular locations: Mitochondrion inner membrane
Isoform 1: Widely expressed . Isoform 2: Expression is barely detectable .
