POST-TRANSLATIONAL MODIFICATION

Phosphorylated by PRKDC and TXK.; Poly-ADP-ribosylated on glutamate and aspartate residues by autocatalysis. Poly-ADP-ribosylated by PARP2; poly-ADP-ribosylation mediates the recruitment of CHD1L to DNA damage sites. ADP-ribosylated on serine by autocatalysis; serine ADP-ribosylation takes place following interaction with HPF1.; S-nitrosylated, leading to inhibit transcription regulation activity.

SUBCELLULAR LOCATION

Nucleus, nucleolus, Cytoplasm, cytosol.

FUNCTION

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. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150. With EEF1A1 and TXK, forms a complex 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. Required for PARP9 and DTX3L recruitment to DNA damage sites. PARP1-dependent PARP9-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites.
