PARP, a 116kD nuclear poly (ADP-ribose) polymerase, appears to be involved in DNA repair in response to environmental stress (1).
This protein can be cleaved by many ICE-like caspases in vitro (2,3) and is one of the main cleavage targets of caspase-3 in vivo (4,5).
In human PARP, the cleavage occurs between Asp214 and Gly215, which separates the PARP N-terminal DNA binding domain (24kD) from the C-terminal catalytic domain (89kD) (2,4).
PARP helps cells to maintain their viability; cleavage of PARP facilitates cellular disassembly and serves as a marker of cells undergoing apoptosis (6).
