Function The beta subunit of voltage-dependent calcium channels contributes to the function of the calcium channel by increasing peak calcium current, shifting the voltage dependencies of activation and inactivation, modulating G protein inhibition and controlling the alpha-1 subunit membrane targeting.
Subcellular Location Cell membrane, sarcolemma; Peripheral membrane protein; Cytoplasmic side.
