The Na(+)-driven Cl-HCO(3) exchanger (NDCBE or SLC4A8) is a member of the solute carrier 4 (SLC4) family of HCO(3)(-) transporters, which includes products of 10 genes with similar sequences. Most SLC4 members play important roles in regulating intracellular pH (pH(i)). Physiological studies suggest that NDCBE is a major pH(i) regulator in at least(More)
NCBE (SLC4A10) is a member of the SLC4 family of bicarbonate transporters, several of which play important roles in intracellular-pH regulation and transepithelial HCO(3)(-) transport. Here we characterize a new antibody that was generated in rabbit against a fusion protein consisting of maltose-binding protein and the first 135 amino acids (aa) of the(More)
In Kv1.1, single point mutants found below the channel activation gate at residue V408 are associated with human episodic ataxia type-1, and impair channel function by accelerating decay of outward current during periods of membrane depolarization and channel opening. This decay is usually attributed to C-type inactivation, but here we provide evidence that(More)
We synthesized 22-fluorovitamin D3 from (22S) cholest-5-ene-3 beta, 22-diol-3 beta-acetate 2. Compound 2 was treated with diethylaminosulfur trifluoride to give 22-fluorocholest-5-en-3 beta-acetate 3 and (E) 22-dehydrocholest-5-en-3 beta-acetate. Compound 3 was treated with N-bromosuccinimide to give a mixture of the respective 5,7- and 4,6-dienes. The(More)
