Inthe platelet activation pathway, the activated PRKCI protein activates theRas-associated protein, RAP-1a, thereby indirectly promoting platelet aggregation.Among the screened genes, a large part has been found to be associated with tumoroccurrence or participating in biological processes such as RNA degradation; yet notall genes were found to be related to the formation of myocardial infarction, andthe roles of some genes are not yet clear. The gene discussed is RAP1A; the disease is myocardial infarction.
