Regulation of activated protein C by a new protein. A possible function for bovine protein S.

Open access
Walker, F.J.·1980·Journal of Biological Chemistry

Abstract

The rate of inactivation of activated Factor V (Factor Va) by activated protein C can be enhanced by the addition of plasma. Plasma alone, however, had no effect upon Factor Va activity. This observation indicated that plasma may contain a cofactor for activated protein C. The cofactor activity was removed from plasma by barium citrate absorption and was eluted from the barium pellet. The cofactor activity eluted slightly ahead of prothrombin when chromatographed on quaternary aminoethyl (QAE)-Sephadex. The activity appeared to co-chromatograph with a protein that has been designated protein S. Purified cofactor-protein S had no effect upon the activity of purified bovine Factor Va either in the presence or in the absence of phospholipid. Purified cofactor-protein S caused a large enhancement in the rate of inactivation of Factor Va by activated protein C in the presence of phospholipid. These results indicate that protein S may be a cofactor for activated protein C.

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.
