Summaries for SLC4A8 Gene

Entrez Gene Summary for SLC4A8 Gene

  • The protein encoded by this gene is a membrane protein that functions to transport sodium and bicarbonate ions across the cell membrane. The encoded protein is important for pH regulation in neurons. The activity of this protein can be inhibited by 4,4'-Di-isothiocyanatostilbene-2,2'-disulfonic acid (DIDS). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

GeneCards Summary for SLC4A8 Gene

SLC4A8 (Solute Carrier Family 4 Member 8) is a Protein Coding gene. Diseases associated with SLC4A8 include Voyeurism and Transvestism. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. Gene Ontology (GO) annotations related to this gene include transporter activity and anion transmembrane transporter activity. An important paralog of this gene is SLC4A10.

UniProtKB/Swiss-Prot for SLC4A8 Gene

  • Mediates electroneutral sodium- and carbonate-dependent chloride-HCO3(-) exchange with a Na(+):HCO3(-) stoichiometry of 2:1. Plays a major role in pH regulation in neurons. May be involved in cell pH regulation by transporting HCO3(-) from blood to cell. Enhanced expression in severe acid stress could be important for cell survival by mediating the influx of HCO3(-) into the cells. Also mediates lithium-dependent HCO3(-) cotransport. May be regulated by osmolarity.
