  • 功能：
    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.
  • 基因功能参考文献：
    1. CA4 is a novel tumour suppressor in Colorectal cancer through the inhibition of the Wnt signalling pathway by targeting the WTAP-WT1-TBL1 axis. CA4 methylation may serve as an independent biomarker for the recurrence of Colorectal cancer . PMID: 26071132
    2. Carbonic anhydrase 4 is lost in papillary thyroid carcinoma but not thyroid nodules PMID: 24880201
    3. Although CA IV has been shown to be active in mediating CO2 and HCO3 (-) transport in many important tissues like kidney and lung, and in isolated cells from brain and muscle, the gene for CA IV appears not to be essential. PMID: 24146379
    4. Coexpression of CAIV with MCT1 and MCT4 resulted in a significant increase in MCT transport activity. PMID: 24338019
    5. membrane-associated CA IV contributes robust catalytic activity intracellularly, and this activity participates in regulating H(+) dynamics in the cytosol PMID: 23297198
    6. Two SNPs of carbonic anhydrase IV, which are responsible for amino acid changes, were found. The frequencies of these SNPs were not significantly different between the caries-free group and the group with caries PMID: 22021688
    7. compared the subcellular localization and post-translational processing of wild-type (WT)- and retinitis pigmentosa 17 mutant-CAIV in three cell types PMID: 20626030
    8. The results suggest that the expression level of carbonic anhydrase IV may be important to maintain retina function in retinitis pigmentosa. PMID: 20450258
    9. renal injury inflicted by expression of human carbonic anhydrase IV folding mutants was markedly enhanced by haploinsufficiency of the endoplasmic reticulum cochaperone p58(IPK). PMID: 20308551
    10. binding by extracellular loop 4 of the human AE1 Cl-/HCO3- exchanger PMID: 11994299
    11. carbonic anhydrase IV binds EC4 of NBC1, and this interaction is essential for full NBC1 activity PMID: 14567693
    12. mutation was found to cosegregate with the retinitis pigmentosa RP17 phenotype in two large families PMID: 15090652
    13. CA inhibitors may have long-term adverse effects on vision. PMID: 15563508
    14. characterized the CA IV expressed in Capan-1 cells PMID: 17409381
    15. A novel mutation has been identified in CA4 that provides further evidence that impaired pH regulation may underlie photoreceptor degeneration in retinitis pigmentosa PMID: 17652713
    16. CAIV p.R14W sequence variant found in one of the patients with Bothnia dystrophy phenotype is benign polymorphism in population of northern Sweden. PMID: 18344446
    17. Apoptosis induced by the CA IV mutants could be prevented, at least partially, by treating the cells with dorzolamide, a CA inhibitor PMID: 19211803
