About CACNA1B

Cytogenetic location: 9q34.3 Genomic coordinates (GRCh38): 9:137,877,782-138,124,619 (from NCBI)

This gene has 5 transcripts (splice variants), 289 orthologues, 26 paralogues and is associated with 3 phenotypes. Biased expression in brain (RPKM 4.9), testis (RPKM 2.2) and 1 other tissue.

Summary

The protein encoded by this gene is the pore-forming subunit of an N-type voltage-dependent Calcium Channel, which controls neurotransmitter release from neurons. The encoded protein forms a complex with alpha-2, beta, and delta subunits to form the high-voltage activated channel. This channel is sensitive to omega-conotoxin-GVIA and omega-agatoxin-IIIA but insensitive to dihydropyridines. Two transcript variants encoding different isoforms have been found for this gene.
