DESCRIPTION

Also known as CACB1_HUMAN, CACNB1, CACNLB1. 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 functional expression L-type calcium channels that contain CACNA1D as pore-forming subunit (PubMed:1309651). Regulates the activity of L-type calcium channels that contain CACNA1B as pore-forming subunit (PubMed:8107964). Regulatory subunit of L-type calcium channels that consist of a pore-forming alpha subunit and auxiliary beta, gamma and delta subunits (By similarity). Interacts with CACNA1A, CACNA1B, CACNA1C and CACNA1S (By similarity). Component of a calcium channel complex consisting of a pore-forming alpha subunit (CACNA1S) and the ancillary subunits CACNB1 or CACNB2, CACNG1 and CACNA2D1. Identified in a complex with CACNA1C (PubMed:15615847). Identified in a complex with the L-type calcium channel subunits CACNA1C, CACNA2D1, CACNB1 and one of the gamma subunits (CACNG4, CACNG6, CACNG7, or CACNG8) (By similarity). Part of a L-type calcium channel complex that contains CACNA1D, CACNA2D1 and CACNB1 (PubMed:1309651). Part of a L-type calcium channel complex that contains CACNA1B, CACNA2D1 and CACNB1 (PubMed:8107964). Interacts with JSRP1. Interacts with RYR1 (By similarity). Interacts with CBARP (By similarity).

Also known as CACB1_HUMAN, CACNB1, CACNLB1. Regulatory subunit of L-type calcium channels (PubMed:1309651, PubMed:8107964, PubMed:15615847). Regulates the activity of L-type calcium channels that ...
