| Function | 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 (By similarity). 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. 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 (By similarity). |
| Subcellular Location | Nucleus. Nucleus, nucleolus {ECO:0000250}. Note=Localizes at sites of DNA damage. {ECO:0000250}. |
| Tissue Specificity | Widely expressed. Expression is correlated with proliferation, with higher levels occurring during early fetal development and organogenesis and in the highly proliferative cell compartments of adult. Expressed in B-cells that have been induced to switch to various Ig isotypes. {ECO:0000269|PubMed:9642267}. |
