Poly [ADP-ribose] polymerase 1 from Human, Recombinant

Cat No.
NATE-0507
Description
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.
Abbr
PARP1, Recombinant (Human)
Alias
PARP1
Source

Species
Human
Applications
PARP-1 is a nuclear enzyme that synthesizes ADP-ribose polymers from NAD+, specifically binds Zn2+ and DNA, and recognizes single-strand breaks in DNA. PARP1 has been used in a study to assess racial and tissue-specific cancer risk ass ociated with polymorphism in the PARP1 gene. It has also been used in a study to investigate inhibitors of PARP-1 for potential cancer treatments.
Form
Supplied as a solution in 20 mM Tris-HCl, pH 8.0, 200 mM NaCl, 1 mM DTT, 0.1% Triton™-X 100, 50 % glycerol, and 0.1 mg/ml BSA.
