Web"Although inward rectifying potassium channels pass current better in the inward than the outward direction, the membrane potential (Vm) is typically never more negative than Ek (equilibrium potential of potassium across the membrane). Thus,net inward K+ current does not occur physiologically. WebIn the inner mitochondrial membrane, several potassium channels that play a role in cell life and death have been identified. One of these channels is the ATP-regulated potassium channel (mitoKATP). The ROMK2 potassium channel is a potential molecular component of the mitoKATP channel. The current study aimed to investigate the pharmacological …
