Anti-acetyl PARP1 Antibody, clone E4

Poly (ADP-ribose) polymerase 1 (PARP1) is zinc-dependent DNA binding protein that recognizes DNA strand breaks and is presumed to play a role in DNA repair. As a marker for apoptosis, PARP is cleaved in vitro by many caspases and in vivo by Caspase-3. Acetylation of PARP1 by p300/CREB-binding protein is important in the regulation of NF-kappaB-dependent gene activation through enhanced functional interactions with p300 and the Mediator complex.

~ 45 kDa observed. Both proteins we provided were acetylated in vitro by p300 using acetyl-CoA. While the short fragment (bacterially expressed) is very nicely acetylated, the full-length (bacolu system) is only weakly modified. The detection of the full-length protein is thus much more difficult.

Linear peptide corresponding to acetylated human PARP1, short fragment.
