Summaries for CACNA2D3 Gene

Entrez Gene Summary for CACNA2D3 Gene

  • This gene encodes a member of the alpha-2/delta subunit family, a protein in the voltage-dependent calcium channel complex. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization and consist of a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. Various versions of each of these subunits exist, either expressed from similar genes or the result of alternative splicing. Research on a highly similar protein in rabbit suggests the protein described in this record is cleaved into alpha-2 and delta subunits. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized. [provided by RefSeq, Jul 2008]

GeneCards Summary for CACNA2D3 Gene

CACNA2D3 (Calcium Channel, Voltage-Dependent, Alpha 2/Delta Subunit 3) is a Protein Coding gene. Diseases associated with CACNA2D3 include zimmermann-laband syndrome and hereditary night blindness. Among its related pathways are MAPK signaling pathway and ERK Signaling. GO annotations related to this gene include voltage-gated calcium channel activity. An important paralog of this gene is CACNA2D4.

UniProtKB/Swiss-Prot for CACNA2D3 Gene

  • The alpha-2/delta subunit of voltage-dependent calcium channels regulates calcium current density and activation/inactivation kinetics of the calcium channel. Acts as a regulatory subunit for P/Q-type calcium channel (CACNA1A), N-type (CACNA1B), L-type (CACNA1C OR CACNA1D) but not T-type (CACNA1G) (By similarity).
