CACNB2

CACNB2 (Calcium Voltage-Gated Channel Auxiliary Subunit Beta 2) is a Protein Coding gene. This gene encodes a subunit of a voltage-dependent calcium channel protein that is a member of the voltage-gated calcium channel superfamily. The gene product was originally identified as an antigen target in Lambert-Eaton myasthenic syndrome, an autoimmune disorder. Diseases associated with CACNB2 include Brugada Syndrome 4 and Lambert-Eaton Myasthenic Syndrome.

Interaction

Component of a calcium channel complex consisting of a pore-forming alpha subunit (CACNA1S) and the ancillary subunits CACNB1 or CACNB2, CACNG1 and CACNA2D1. The channel complex contains alpha, beta, gamma and delta subunits in a 1:1:1:1 ratio, i.e. it contains either CACNB1 or CACNB2. Interacts with CACNA1C (By similarity). Interacts with RRAD. Interaction with RRAD regulates the trafficking of CACNA1C to the cell membrane (PubMed:17525370). Interacts with TMIGD2 (PubMed:22419821). Interacts with CAMK2D. Interacts with CBARP (By similarity). Interacts with CAMK2A (PubMed:28130356).
