Phosphatidylinositol 4,5-Diphosphate 30-35 coagulation factor II, thrombin Homo sapiens 0-8 6324792-4 1984 Thrombin-induced decreases in PI-P2 content could account for release of sufficient membrane-bound Ca to raise cytoplasmic free [Ca2+] to 1-2 microM, supporting the hypothesis that PI-P2 represents the Ca-binding site involved in the stimulus-dependent increase in cytoplasmic Ca2+ evoked by receptor-ligand interactions. Phosphatidylinositol 4,5-Diphosphate 181-186 coagulation factor II, thrombin Homo sapiens 0-8 6296123-1 1983 The addition of thrombin to human platelets prelabeled with 32Pi led to significant loss of radioactivity in phosphatidylinositol 4,5-bisphosphate within 5 s, followed by recovery or even increase by 2 min. Phosphatidylinositol 4,5-Diphosphate 109-146 coagulation factor II, thrombin Homo sapiens 16-24 6301436-2 1983 The addition of thrombin to [3H]glycerol-labeled platelets induced an initial loss and a subsequent increase of the radioactivity in phosphatidylinositol-4,5-bisphosphate (TPI) without any significant change in phosphatidylinositol-4-phosphate (DPI).
