Web10 Jan 2013 · When poly(A) polymerase was PARylated, RNA binding to poly(A) polymerase decreased, but no effect on assembly of the 3′ processing complex was detected. Together these results identify poly(A) polymerase as a new PARP1 substrate and show that poly(A) polymerase function is regulated by PARylation in a PARP1-dependent manner. WebFurthermore, we define the effects that PARP1, PARylated PARP1, and PAR have on RECQL5 and WRN, using both in vitro and in vivo assays. We show that PARylation is involved in the recruitment of RECQL5 and WRN to laser-induced DNA damage and that RECQL5 and WRN have differential responses to PARylated PARP1 and PAR.
