PF00645Poly(ADP-ribose) polymerase and DNA-Ligase Zn-finger region (zf-PARP)Poly(ADP-ribose) polymerase and DNA-Ligase Zn-finger regionPoly(ADP-ribose) polymerase is an important regulatory component of the cellular response to DNA damage. The amino-terminal region of Poly(ADP-ribose) polymerase consists of two PARP-type zinc fingers. This region acts as a DNA nick sensor. Domain
