function:Outwardly rectifying potassium channel subunit that may co-assemble with other Slo-type channel subunits. Activated by high intracellular sodium or chloride levels. Activated upon stimulation of G-protein coupled receptors, such as CHRM1 and GRIA1. May be regulated by calcium in the absence of sodium ions (in vitro).,PTM:Phosphorylated by protein kinase C. Phosphorylation of the C-terminal domain increases channel activity.,similarity:Belongs to the potassium channel family. Calcium-activated subfamily.,similarity:Contains 1 RCK N-terminal domain.,subunit:Interacts with CRBN via its cytoplasmic C-terminus.,tissue specificity:Highest expression in liver, brain and spinal cord. Lowest expression in skeletal muscle.,
Cell membrane ; Multi-pass membrane protein .
Highest expression in liver, brain and spinal cord. Lowest expression in skeletal muscle.
