General description

Poly(ADP-ribose) polymerase 1 (PARP-1) is associated with the inflammation response during atherosclerosis.
Poly(ADP-ribose) polymerase 1 (PARP1) belongs to the PARP family which is highly conserved during evolution. PARP1 gene is localized at 1q42.12 in the human chromosome.

Application

PARP-1 human has been used in the GST-pull down assay for immunoprecipitation of Glutathione S-transferase (GST) or GST- cyclic GMP- AMP synthase (cGAS) (GST-cGAS). It has also been used in in vitro ribosylation assay.
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 associated with polymorphism in the PARP1 gene. It has also been used in a study to investigate inhibitors of PARP-1 for potential cancer treatments.

Biochem/physiol Actions

PARP-1 is inactivated by cleavage into a 24kDA and 89kDA fragment by activated caspase-3 or caspase-7. This results in the decreased ability to repair DNA damage and an increase in apoptosis.
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.
Poly(ADP-ribose) polymerase 1 (PARP1) is essential for diverse functions like DNA damage detection and repair, chromatin modification, cell differentiation, transcription and apoptotic cell death. It also plays a major role in spermatogenesis. Polymorphism in the gene PARP1 is associated with oligospermia and causes male infertility.

Atherosclerosis begins as local inflammation of vessels at sites of disturbed flow, where low shear stress (LSS) leads to mechanical irritation and plaque development and progression. Nuclear enzyme poly(ADP-ribose) polymerase 1 (PARP-1) is associated with the inflammation response during atherosclerosis.
