== Function ==
[https://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>

== Publication Abstract from PubMed ==
The ubiquitin-specific protease (USP) family of deubiquitinases (DUBs) are regulators of Ub signaling that share a common catalytic-domain fold. The dynamic nature of this domain is important for controlling the function of USPs, with inter- and intramolecular interactions often influencing the structure and enzymatic activity of these DUBs. This conformational flexibility, in combination with the high sequence conservation of the USP active site, has made it challenging to readily identify potent and selective inhibitors for individual USPs. Here, we demonstrate how a naive, macrocycle-mRNA display selection rapidly yielded high-affinity binders to USP7 that specifically inhibit the DUB with nanomolar half-maximal inhibitory concentration (IC(50)) values. Structural analysis of the macrocycles bound to USP7 revealed a variety of binding modes and identified inhibition hotspots on the enzyme that mirror those used by small-molecule inhibitors. Together, these data suggest that initial macrocyclic hits could serve as pivotal tools in developing USP-specific inhibitors and probing USP biology.
