Function | ATP-binding subunit of the mitochondrial ATP-gated potassium channel (mitoK(ATP)). Together with pore-forming subunit CCDC51/MITOK of the mitoK(ATP) channel, mediates ATP-dependent potassium currents across the mitochondrial inner membrane. An increase in ATP intracellular levels closes the channel, inhibiting K(+) transport, whereas a decrease in ATP levels enhances K(+) uptake in the mitochondrial matrix. Plays a role in mitochondrial iron transport. Required for maintenance of normal cardiac function, possibly by influencing mitochondrial iron export and regulating the maturation of cytosolic iron sulfur cluster-containing enzymes. |
