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.SUBUNIT The L-type calcium channel is composed of four subunits: alpha-1, alpha-2, beta and gamma (PubMed:11880487). Interacts with FASLG (PubMed:19807924). Interacts with CBARP (By similarity).INTERACTION Expressed predominantly in the cerebellum and kidney.DISEASE Disease susceptibility is associated with variants affecting the gene represented in this entry.DISEASE Disease susceptibility is associated with variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.MISCELLANEOUS Unable to interact with the alpha-1 subunit.SIMILARITY Belongs to the calcium channel beta subunit family.
