UniProtKB - Q9MZL3 (CACB3_BOVIN)
Voltage-dependent L-type calcium channel subunit beta-3
CACNB3
Functioni
Regulatory subunit of the voltage-gated calcium channel that gives rise to L-type calcium currents (PubMed:10684870).
Increases CACNA1B peak calcium current and shifts the voltage dependencies of channel activation and inactivation (PubMed:10684870).
Increases CACNA1C peak calcium current and shifts the voltage dependencies of channel activation and inactivation (By similarity).

Interactioni
Subunit structurei
Component of a calcium channel complex consisting of a pore-forming alpha subunit (CACNA1C) and the ancillary subunits CACNB3 and CACNA2D1. The channel complex contains alpha, beta, gamma and delta subunits in a 1:1:1:1 ratio.
Interacts with CACNA2D4.
Interacts with FASLG (By similarity).
Interacts with CBARP; prevents the interaction of CACNB3 with the alpha subunit CACNA1C thereby negatively regulating the activity of the corresponding calcium channel (By similarity).
