Fusing the CTD of p53 to GST renders GST a target for covalent PARylation. (A) In-vitro PARylation assay with 97 pmol GST, GST-p53_325–393 or GST-p53_359–387. In comparison, covalent PARylation of 5 pmol p53_WT is shown. (B) Thrombin cleavage assay with covalently PARylated GST-p53_325–393. Down-shifted bands are indicated by red brackets, bands of non-thrombin-treated samples by blue brackets. (C) Thrombin cleavage assay with covalently PARylated GST-p53_359–387.
