Webb22 jan. 2024 · Current evidence also supports histone H1 as the likely substrate of ubiquitination ( 24 ). In addition to γH2AX and ubH2A, histones are also poly (ADP-ribosyl)ated at multiple sites by poly (ADP-ribose) polymerases (PARPs) in response to both single-stranded breaks (SSBs) and DSBs mediated DNA damage ( 25–30 ). Webb3 nov. 2024 · The recently discovered Histone PARylation Factor 1 (HPF1) modulates the enzymatic activity of PARP1 and PARP2 by redirecting their specificity from Asp and Glu to Ser amino acid side chains, and by redirecting both enzymes to more efficiently PARylate histones in trans (in addition to their auto-modification in cis) [ 18 ]. richard tierney obituaryWebb20 mars 2024 · PARylation is implicated in modulating the activity of histone and chromatin modifying enzymes at the different chromatin levels: a.
