Voltage-dependent L-type calcium channel subunit beta-2

UniProtKB accession:  Q8VGC3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Beta subunit of voltage-dependent calcium channels which contributes to the function of the calcium channel by increasing peak calcium current (PubMed:1370480, PubMed:12042350). Plays a role in shifting voltage dependencies of activation and inactivation of the channel (PubMed:1370480, PubMed:12042350). May modulate G protein inhibition (PubMed:11604404, PubMed:12042350, PubMed:1370480). May contribute to beta-adrenergic augmentation of Ca(2+) influx in cardiomyocytes, thereby regulating increases in heart rate and contractile force (By similarity). Involved in membrane targeting of the alpha-1 subunit CACNA1C (By similarity).
