P04637	P09874	0	relocalization	up-regulates activity	0.559	We identify the major poly(ADP-ribosyl)ated sites of p53 by PARP-1 and find that PARP-1-mediated poly(ADP-ribosyl)ation blocks the interaction between p53 and the nuclear export receptor Crm1, resulting in nuclear accumulation of p53. These findings molecularly link PARP-1 and p53 in the DNA-damage response, providing the mechanism for how p53 accumulates in the nucleus in response to DNA damage.\|PARP-1 is super-activated by binding to damaged DNA, and poly(ADP-ribosyl)ates p53.
