The first member of this family to be characterized was a respiratory epithelium, Ca found a row in 1A13.INFO that was not parsed out 2+-regulated, chloride channel protein isolated from bovine tracheal apical membranes. It was biochemically characterized as a 140 kDa complex. The purified found a row in 1A13.INFO that was not parsed out complex when reconstituted in a planar lipid bilayer behaved as an anion-selective channel. It was regulated by Ca 2+ via a calmodulin kinase II-dependent found a row in 1A13.INFO that was not parsed out mechanism. When the cRNA was injected into Xenopus oocytes, an outward rectifying, DIDS-sensitive, anion conductance was measured. A related gene, found a row in 1A13.INFO that was not parsed out Lu-ECAM, was cloned from the bovine aortic endothelial cell line, BAEC. It is expressed in the lung and spleen but not in the trachea. Homologues are found in found a row in 1A13.INFO that was not parsed out several mammals, and at least three paralogues(hCaCC-1-3) are present in humans, each with different tissue distributions. found a row in 1A13.INFO that was not parsed out
