| + | [[http://www.uniprot.org/uniprot/TIRR_MOUSE TIRR_MOUSE]] Key regulator of TP53BP1 required to stabilize TP53BP1 and regulate its recruitment to chromatin. In absence of DNA damage, interacts with the tandem Tudor-like domain of TP53BP1, masking the region that binds histone H4 dimethylated at 'Lys-20' (H4K20me2), thereby preventing TP53BP1 recruitment to chromatin and maintaining TP53BP1 localization to the nucleus. Following DNA damage, ATM-induced phosphorylation of TP53BP1 and subsequent recruitment of RIF1 leads to dissociate NUDT16L1/TIRR from TP53BP1, unmasking the tandem Tudor-like domain and allowing recruitment of TP53BP1 to DNA double strand breaks (DSBs). Binds U8 snoRNA.[UniProtKB:Q9BRJ7] [[http://www.uniprot.org/uniprot/TP53B_HUMAN TP53B_HUMAN]] Plays a key role in the response to DNA damage. May have a role in checkpoint signaling during mitosis.
