Summary
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]

    Title: Genes, biomarkers, and clinical features associated with the course of bipolar disorder.
  3. Results found that CACNA2D3 was lowly expressed in endometrial cancer (EC) tissues and cells. Its overexpression significantly blocked the tumor growth in an in vivo xenograft model while in vitro, it inhibited cell proliferation and migration, and promoted apoptosis and calcium influx. These data revealed that CACNA2D3 functions as a tumor suppressor in EC.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
