No evidence for structural or functional identity between p24/CD9 and p21/ras.
Experiments were undertaken to test the hypothesis that the p24/CD9 cell surface molecule (originally detected on acute lymphoblastic leukemia cells) and the p21 protein encoded by the ras gene family are related. Immunoprecipitation and guanine nucleotide binding assays conducted with BA-2 and anti-p21/ras monoclonal antibodies showed no evidence that p24/CD9 is structurally or functionally related to p21/ras.
