CACNB2 - calcium voltage-gated channel auxiliary subunit beta 2 Gene

Also Known as CAB2; MYSB; CAVB2; CACNLB2

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 783

About CACNB2

Cytogenetic location: 10p12.33-p12.31 Genomic coordinates (GRCh38): 10:18,140,424-18,543,557 (from NCBI)

This gene has 26 transcripts (splice variants), 199 orthologues, 3 paralogues and is associated with 2 phenotypes. Ubiquitous expression in brain (RPKM 4.0), adrenal (RPKM 2.4) and 25 other tissues.

Summary

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. Mutations in this gene are associated with Brugada syndrome. Alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq, Feb 2013]
