Right: DTX3L allows PARP9 to ADP-ribosylate ubiquitin, possibly by recruiting an E2-Ub conjugate to the PARP active site. buckingham palace interesting factsWebThe strong HPF1-PARP1 interaction is opposed by an autoinhibitory region of PARP1. This region is known to locally unfold on binding DNA lesions. Therefore, the authors propose that the complex formation is a regulatory mechanism restricting PARP1 activity until suitable cues, such as DNA damage induced PARP1 DNA binding, present themselves. buckingham palace interiors
