Voltage-dependent L-type calcium channel subunit beta-1

UniProtKB accession:  P19517

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Regulatory subunit of L-type calcium channels (PubMed:7509046). Regulates the activity of L-type calcium channels that contain CACNA1A as pore-forming subunit (PubMed:7509046). 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. Required for functional expression L-type calcium channels that contain CACNA1D as pore-forming subunit. Regulates the activity of L-type calcium channels that contain CACNA1B as pore-forming subunit (By similarity).
