Summaries for CA4 Gene

Entrez Gene Summary for CA4 Gene

  • Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization. This gene encodes a glycosylphosphatidyl-inositol-anchored membrane isozyme expressed on the luminal surfaces of pulmonary (and certain other) capillaries and proximal renal tubules. Its exact function is not known; however, it may have a role in inherited renal abnormalities of bicarbonate transport. [provided by RefSeq, Jul 2008]

GeneCards Summary for CA4 Gene

CA4 (Carbonic Anhydrase IV) is a Protein Coding gene. Diseases associated with CA4 include retinitis pigmentosa 17 and ca4-related retinitis pigmentosa. Among its related pathways are Metabolism and Proximal tubule bicarbonate reclamation. GO annotations related to this gene include carbonate dehydratase activity. An important paralog of this gene is CA14.

UniProtKB/Swiss-Prot for CA4 Gene

  • Reversible hydration of carbon dioxide. May stimulate the sodium/bicarbonate transporter activity of SLC4A4 that acts in pH homeostasis. It is essential for acid overload removal from the retina and retina epithelium, and acid release in the choriocapillaris in the choroid.

Tocris Summary for CA4 Gene

  • Carbonic anhydrases (EC 4.2.1.1) are zinc-containing enzymes belonging to the lyases family, and are primarily responsible for catalyzing the reversible hydration of carbon dioxide to form bicarbonate (HCO3-) and hydrogen (H+) ions.

  • Retinitis pigmentosa 17 (RP17) [MIM:600852]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:15563508, ECO:0000269 PubMed:17652713, ECO:0000269 PubMed:20450258}. Note=The disease is caused by mutations affecting the gene represented in this entry. Defective acid overload removal from retina and retinal epithelium, due to mutant CA4, is responsible for photoreceptor degeneration, indicating that impaired pH homeostasis is the most likely cause underlying the RP17 phenotype.
