Facts about Voltage-dependent L-type calcium channel subunit beta-1.
Regulates the activity of L-type calcium channels that contain CACNA1C as pore-forming subunit and increases the presence of the channel complex at the cell membrane (PubMed:15615847). Required for practical expression L-type calcium channels that contain CACNA1D as pore-forming subunit (PubMed:1309651).
