Recombinant Human PARP1, HA-tagged

Cat.No.: PARP1-451H
Product Overview: Human full-length inactive mutant E998K of PARP-1 is fused to a HA-tag and a His-tag.
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-gamma to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production. PARP-1 (E998K mutant) is an inactive form of PARP-1 which can be used as a control compound.
