Poly (ADP-ribose) polymerase (PARP) is involved in DNA repair and programmed cell death. The PARP family contains 17 members. PARP is composed of 4 domains. Among them are the N terminal DNA-binding domain which contains 2 zinc fingers; auto modification domain which contains a WGR-rich domain; C terminal which includes the catalytic domain (or PARP domain). PARP-10 contains a RNA recognition motif (RRM). Tankyrase (Tank) is a PARP which contains ankyrin repeats (a 33-residue repeat with 2 α-helices separated by loops).
