| Tissue Specificity | Expressed in fibroblasts, retinal pigmented epithelial cells and lymphoblastoid cells (at protein level). |
| Post Translational Modifications | Phosphorylation of Ser-371 causes dimer dissociation. Phosphorylation by CK2 promotes interaction with APTX and APLF. Sumoylated. |
| Function | Scaffold protein involved in DNA single-strand break repair by mediating the assembly of DNA break repair protein complexes. Negatively regulates ADP-ribosyltransferase activity of PARP1 during base-excision repair in order to prevent excessive PARP1 activity. Recognizes and binds poly-ADP-ribose chains: specifically binds auto-poly-ADP-ribosylated PARP1, limiting its activity. |
