Human Gene Set: RAHMAN_TP53_TARGETS_PHOSPHORYLATED


Standard name RAHMAN_TP53_TARGETS_PHOSPHORYLATED
Systematic name M1333
Brief description Proteins phosporylated in HCT116 cells (colon cancer) upon p53 [GeneID=7157] activation.
Full description or abstract The p53 tumor suppressor regulates transcription of target genes. We have previously analysed the p53-dependent proteome and identified novel protein targets. Here we have examined p53-dependent phosphorylation using two-dimensional gel electrophoresis and staining with the fluorescent phosphoprotein dye Pro-Q Diamond. We report that p53 induces phosphorylation of a subset of proteins including Nm23, DJ-1, ANXA1 and PrxII. Our identification of p53-dependent phosphorylation of specific target proteins reveals new aspects of the p53-dependent cellular response and suggests that such posttranslational modifications may contribute to p53-mediated tumor suppression.
