Ouabain-sensitive (Na+ + K+)-ATPase activity expressed in mouse L cells by transfection with DNA encoding the alpha-subunit of an avian sodium pump.
Open accessAbstract
cDNA encoding the alpha-subunit of the (Na+ + K+)-ATPase was cloned from a chicken kidney cDNA library and the nucleotide sequence determined. The deduced amino acid sequence showed 92% sequence homology with the alpha-subunit of the sheep kidney (Na+ + K+)-ATPase, and high cross-species homologies were found among nucleotide sequences both in the 5'- and 3'-untranslated regions of the "kidney-type" alpha-subunit mRNAs. The cDNA was subcloned into a shuttle vector derived from pSV2CAT and was stably incorporated into mouse Ltk- cells. Expression of the avian alpha-sub-unit could be activated by culture of the cells in 10 mM butyrate. Cells expressing avian alpha-subunits displayed high-affinity ouabain binding (KD = 2.6 +/- 0.7 x 10(-7) M) and ouabain-sensitive 86Rb+ uptake, characteristic of avian cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
