Gene expression of Na+-K+-ATPase alpha 1 and alpha 3 subunits in gills of the teleost Oreochromis mossambicus, adapted to different environmental salinities.

Abstract

The objective of the present study was to test the hypothesis that fish gills can express more than one isoform of the Na+-K+-ATPase a subunit responsible for ion regulation in seawater and freshwater environments. Using rapid amplification of complementary DNA ends (RACE), we cloned and sequenced full-length cDNAs encoding Na+-K+-ATPase alpha 1 and alpha 3… (More)
