== Publication Abstract from PubMed ==

The ubiquitin-specific protease, USP7, has key roles in the p53 pathway whereby it stabilizes both p53 and MDM2. We show that the N-terminal domain of USP7 binds two closely spaced 4-residue sites in both p53 and MDM2, falling between p53 residues 359-367 and MDM2 residues 147-159. Cocrystal structures with USP7 were determined for both p53 peptides and for one MDM2 peptide. These peptides bind the same surface of USP7 as Epstein-Barr nuclear antigen-1, explaining the competitive nature of the interactions. The structures and mutagenesis data indicate a preference for a P/AXXS motif in peptides that bind USP7. Contacts made by serine are identical and crucial for all peptides, and Trp165 in the peptide-binding pocket of USP7 is also crucial. These results help to elucidate the mechanism of substrate recognition by USP7 and the regulation of the p53 pathway.

[[http://www.uniprot.org/uniprot/UBP7_HUMAN UBP7_HUMAN]] Hydrolase that deubiquitinates target proteins such as FOXO4, p53/TP53, MDM2, ERCC6, DNMT1, UHRF1, PTEN and DAXX. Together with DAXX, prevents MDM2 self-ubiquitination and enhances the E3 ligase activity of MDM2 towards p53/TP53, thereby promoting p53/TP53 ubiquitination and proteasomal degradation. Deubiquitinates p53/TP53 and MDM2 and strongly stabilizes p53/TP53 even in the presence of excess MDM2, and also induces p53/TP53-dependent cell growth repression and apoptosis. Deubiquitination of FOXO4 in presence of hydrogen peroxide is not dependent on p53/TP53 and inhibits FOXO4-induced transcriptional activity. In association with DAXX, is involved in the deubiquitination and translocation of PTEN from the nucleus to the cytoplasm, both processes that are counteracted by PML. Involved in cell proliferation during early embryonic development. Involved in transcription-coupled nucleotide excision repair (TC-NER) in response to UV damage: recruited to DNA damage sites following interaction with KIAA1530/UVSSA and promotes deubiquitination of ERCC6, preventing UV-induced degradation of ERCC6. Contributes to the overall stabilization and trans-activation capability of the herpesvirus 1 trans-acting transcriptional protein ICP0/VMW110 during HSV-1 infection. Involved in maintenance of DNA methylation via its interaction with UHRF1 and DNMT1: acts by mediating deubiquitination of UHRF1 and DNMT1, preventing their degradation and promoting DNA methylation by DNMT1. Exhibits a preference towards 'Lys-48'-linked Ubiquitin chains.<ref>PMID:11923872</ref><ref>PMID:14506283</ref><ref>PMID:15053880</ref><ref>PMID:16160161</ref><ref>PMID:16964248</ref><ref>PMID:18716620</ref><ref>PMID:18590780</ref><ref>PMID:20153724</ref><ref>PMID:21745816</ref><ref>PMID:22411829</ref><ref>PMID:22689415</ref><ref>PMID:22466611</ref><ref>PMID:22466612</ref>
