Thrombin and thrombin receptor agonist peptide induce tyrosine phosphorylation and tyrosine kinases in the platelet cytoskeleton. Translocation of pp60c-src and integrin alpha IIb beta 3 (glycoprotein IIb/IIIa) is not required for aggregation, but is dependent on formation of large aggregate structures.

The maximal aggregation of platelets induced by alpha-thrombin or by the receptor agonist peptide thrombin-(42-47)-peptide (TRP42/47) rapidly increased the pp60c-src associated with the cytoskeleton fraction. There was good correlation between the tyrosine kinase activity and the mass of pp60c-src....
