설명

일반 설명

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.

애플리케이션

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.

생화학적/생리학적 작용

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.
