Voltage-dependent L-type calcium channel subunit beta-1 (CACNB1)

Regulatory subunit of L-type calcium channels (PubMed:1309651, PubMed:8107964, PubMed:15615847). Regulates the activity of L-type calcium channels that contain CACNA1A as pore- forming subunit (By similarity).

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).
