Tyrosine 76-84 tumor protein p53 Homo sapiens 50-53 1506270-6 1992 These results demonstrated that the growth inhibition by anchorage-deficiency or by herbimycin A is associated with an elevated p53 level and reduced p53 phosphorylation at tyrosine. Tyrosine 173-181 tumor protein p53 Homo sapiens 150-153
