Description : PARP-1 (ARTD1) is involved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks. PARP-1 positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150. It forms a complex with EEF1A1 and TXK that acts as a T-helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFN-γ to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production.

Q&As (6)

Ask a question
Does PARP1 protein cause cells to die in time? 12/30/2022

Yes, overactivation of the PARP1 protein can lead to apoptosis or necrosis of cells, which may be exploited in the treatment of certain diseases.

How is the PARP1 protein involved in DNA repair? 02/25/2022

The PARP1 protein can repair DNA damage by attaching ADP-ribose groups to damaged DNA strands and recruiting other repair proteins.

What are the other regulatory mechanisms of PARP1 protein in DNA damage repair? 01/07/2022

In addition to PARP1's involvement in direct DNA repair, it can also modulate the selection of repair pathways and initiate other DNA damage sensing mechanisms.

What is the potential of PARP1 protein in tumor immunotherapy? 09/29/2019

Some studies have proposed that the interaction of PARP1 protein with DNA damage in tumor immunotherapy may affect the efficacy of immunotherapy.

Is PARP1 protein involved in cell cycle regulation? 05/19/2019

Yes, the PARP1 protein is involved in the normal regulation of the cell cycle, especially G1/S and G2/M switching during DNA damage.

What are the effects of overactivation of PARP1 protein on cells? 01/07/2019

Overactivation of PARP1 depletes energy stores such as NAD+ and ATP and leads to apoptosis, or cell death.

    This range of applications of PARP1 is breathtaking, and it can play an important role in any field.

    12/02/2019

      This short half-life and high clearance of PARP1 make it have greater potential in the treatment of tumors, infections and other diseases, and it is expected to become a new generation of therapeutic drugs.

      03/18/2019

        The purity and bioactivity of PARP1 make it a valuable resource for scientific research.
