InnateDB Gene IDBG-45318 (CACNB1)
Protein Structure
UniProt Annotation
Function The beta subunit of voltage-dependent calcium channels contributes to the function of the calcium channel by increasing peak calcium current, shifting the voltage dependencies of activation and inactivation, modulating G protein inhibition and controlling the alpha-1 subunit membrane targeting.
Subcellular Localization Cell membrane, sarcolemma; Peripheral membrane protein; Cytoplasmic side.
Disease Associations
Tissue Specificity Isoform 1 and isoform 3 are expressed in brain, heart, spleen, central nervous system and neuroblastoma cells. Isoform 2 is expressed in skeletal muscle. {ECO:0000269PubMed:8107964}.
