Summary

CACNB1 (calcium voltage-gated channel auxiliary subunit beta 1, HGNC:1401) is a protein-coding gene on chromosome 17q12, encoding Voltage-dependent L-type calcium channel subunit beta-1 (Q02641). Regulatory subunit of L-type calcium channels.

The protein encoded by this gene belongs to the calcium channel beta subunit family. It plays an important role in the calcium channel by modulating G protein inhibition, increasing peak calcium current, controlling the alpha-1 subunit membrane targeting and shifting the voltage dependence of activation and inactivation. Alternative splicing occurs at this locus and three transcript variants encoding three distinct isoforms have been identified.
