24880201 Carbonic anhydrase 4 is lost in papillary thyroid carcinoma but not thyroid nodules
24338019 Coexpression of CAIV with MCT1 and MCT4 resulted in a significant increase in MCT transport activity.
24146379 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.
23297198 membrane-associated CA IV contributes robust catalytic activity intracellularly, and this activity participates in regulating H(+) dynamics in the cytosol
23049597 The generation of CA III and IV autoantibodies, antioxidant enzymes, and cytokines might influence each other.
22021688 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
21680735 data suggest that extracellular membrane-bound CAIV, but not cytosolic CAII, augments transport activity of MCT2 in a non-catalytic manner, possibly by facilitating a proton pathway other than His-88
20801516 Observational study of genetic testing. (HuGE Navigator)
20626030 compared the subcellular localization and post-translational processing of wild-type (WT)- and retinitis pigmentosa 17 mutant-CAIV in three cell types
20450258 The results suggest that the expression level of carbonic anhydrase IV may be important to maintain retina function in retinitis pigmentosa.
20308551 renal injury inflicted by expression of human carbonic anhydrase IV folding mutants was markedly enhanced by haploinsufficiency of the endoplasmic reticulum cochaperone p58(IPK).
19211803 Apoptosis induced by the CA IV mutants could be prevented, at least partially, by treating the cells with dorzolamide, a CA inhibitor
18344446 CAIV p.R14W sequence variant found in one of the patients with Bothnia dystrophy phenotype is benign polymorphism in population of northern Sweden.
17881426 No mutation was found in the coding regions and intron-exon boundaries of the genes for CA II, CA IV, CA XIV, kNCB1, NHE3, NHE8, NHRF1, NHRF2 and SLC26A6 amplified from genomic DNA of family members with pRTA.
17652713 A novel mutation has been identified in CA4 that provides further evidence that impaired pH regulation may underlie photoreceptor degeneration in retinitis pigmentosa
17409381 characterized the CA IV expressed in Capan-1 cells
15563508 CA inhibitors may have long-term adverse effects on vision.
15090652 mutation was found to cosegregate with the retinitis pigmentosa RP17 phenotype in two large families
14567693 carbonic anhydrase IV binds EC4 of NBC1, and this interaction is essential for full NBC1 activity
