Abstract

Proteins of the annexin/lipocortin family act as in vitro anticoagulants by binding to anionic phospholipid vesicles. In this study, we investigated whether annexin V (placental anticoagulant protein I) would bind to human platelets. Annexin V bound to unstimulated platelets in a reversible, calcium-dependent reaction with an apparent Kd of 7 nM and 5000-8000 sites/platelet. Additional binding sites could be induced by several platelet agonists in the following order of effectiveness: A23187 greater than collagen + thrombin greater than collagen greater than thrombin. However, neither ADP nor epinephrine induced additional binding sites. Three other proteins of the annexin family (annexins II, III, and IV) competed for annexin V platelets binding sites with the same relative potencies previously observed for binding to phospholipid vesicles. Phospholipid vesicles containing phosphatidylserine completely inhibited binding of annexin V to platelets. Annexin V completely blocked binding of 125I-factor Xa to thrombin-stimulated platelets. These results support the hypothesis that phosphatidylserine exposure occurs during platelet activation and may be necessary for assembly of the prothrombinase complex on platelet membranes.

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.
