Poly [ADP-ribose] polymerase 1 from Human, Recombinant
PARP-1, a nuclear enzyme that synthesizes ADP-ribose polymers from NAD, specifically binds Zn2+ and DNA, and recognizes single-strand breaks in DNA. It is involved in base excision repair, both short-patch and long-patch, rejoining DNA strand breaks and plays a role in p53 expression and activation. A high level of basal neuronal DNA damage and PARP activity has been reported in rat brain tissue. PARP-1 was shown to be required for HIV-1 integration into DNA. If PARP-1 is deficient there is no productive HIV-1 infection. Applications: Parp-1 is a nuclear enzyme that synthesizes adp-ribose polymers from nad+, specifically binds zn2+ and dna, and recognizes single-st...enosine-diphosphate-D-ribosyl)-acceptor ADP-D-ribosyl-transferase; EC 2.4.2.30.
