"The N-terminal region of Bat3 containing an ubiquitin-linked domain was found to have capacity to form a stable complex with both HAUSP ( xref , lane 3) and p53 ( xref , lane 3), but other deletions, which are lacking the N-terminus, completely abolish the ability to form complexes ( xref , lanes 4 and 5; xref , lanes 5 and 6)."

"P53, as a tumour-suppressor, exerts an essential role in signalling associated with the control of cell survival and aberrant p53 signalling results in unchecked cell growth and the initiation of cancer.USP7 interacts with a range of protein targets in the p53 pathway (p53, MDMX, MDM2)39 and MDM2 plays a key role in p53 stabilization by increasing the ubiquitination process.39 USP7 deubiquitinates MDM2 and its functional regulator MdmX and stabilizes p53.39 USP7 apparently has 2 independent p53 regulatory functions, stabilizing p53 through deubiquitylation and regulating the sequence-specific DNA binding of p53.40 Within the USP7, MDM2 and p53 complex, p53 and the MDM2 have been shown to bind USP7 through the TRAF domain.39 Under normal conditions, USP7 prefers MDM2 as a substrate rather than p53 and MDM2 has a higher binding affinity for USP7 compared to p53.41 Reduction of USP7 expression levels leads to p53 stabilisation, and destabilization of MDM2."

"Notably, we revealed that a p53–HAUSP–Bat3 trimeric protein complex could exist in vivo with HAUSP serving as a binding mediator for enhanced interaction between p53 and Bat3, which antagonizes the interaction of p53 with its proteasome receptor S5a and promotes the accumulation of p53 in the nucleus."

"These results suggest that the formation of p53–HAUSP–Bat3 complex may prevent p53 from being recognized and binding to its proteasome receptor S5a, subsequently leading to the accumulation and stabilization of p53 in nucleus ( xref ) though we still do not know whether there is conformational change in Bat3 and p53 at present."

"As shown in xref , p53 has 393 amino acid residues that can be subdivided into five domains: the N-terminal transactivation domains (TAD) that are responsible for its binding to the p53-binding sites on MDM2 and MDMX, a proline-rich region (PP) that contains five PxxP motifs and is essential for inducing apoptosis, a DNA-binding domain (DBD), a tetramerization domain (TET), and a C-terminal domain (CTD) that is critical for the binding of p53 to the TRAF domain of USP7 ( xref ; xref )."

"Although the essential role of USPs in protein degradation is well established, less is known about the function and regulation of specific family members: for example Usp7 has been associated with p53 and Akt turnover, Usp8 with receptor tyrosine endocytosis, Usp33 with the Von Hippel–Lindau disease (VHL) pathway and Usp19 is thought to have a role in muscle development [ xref ]."

"In addition to the altered levels of HDM2, p53 and p21 associated with its use, P22077 treatment also caused reduced levels of DNA damage proteins DDB1, RBX1, DCAF7 and DCAF11, all of which are subunits of E3 ligases, indicating a previously unknown functional link between USP7 and enzymes involved in DNA repair [ xref ]."

"The results of the interaction between the USP7 and FOXO4 in H1299 human lung carcinoma cells that lack p53 suggested that the interaction is p53 independent. xref , xref However, p53 and FOXOs have noticeable similarities such as the ability to stimulate cell-cycle arrest and cell death and they are both regulated by USP7. xref "

"The findings suggest an additional mechanism underlying the regulation of spermatogonial p53 function, indicating the significance of TSPY1 in germline homeostasis maintenance and the potential of TSPY1 in regulating human spermatogonial proliferation via the USP7 mediated p53 signaling pathway."

"XREF_BIBR - XREF_BIBR USP7 deubiquitinates and stabilizes not only p53, but also Mdm2, the primary E3 ubiquitin ligase of p53 XREF_BIBR, XREF_BIBR Given that both p53 and Mdm2 are known regulators of the steady-level of Poleta, we speculated that changes in cellular USP7 levels may also modulate Poleta level."

"Although several Daxx interacting proteins are involved in critical cellular pathways regarding P53 degradation, such as ubiquitin-specific-processing protease 7 (USP7) and mouse double minute 2 (Mdm2) [XREF_BIBR, XREF_BIBR], it is still unclear whether Daxx has any role in tumorigenicity of OSCC."

"However, p53 levels in P5091‐treated WI‐38 SnCs remained slightly lower than the basal level of p53 in untreated non‐SnCs, suggesting that USP7 inhibition only partially restored the basal levels of p53 in WI‐38 SnCs and did not dramatically increase p53 expression as seen in WI‐38 cells after exposure to IR (Figure 1a, c)."

"In HEK293 cells, we observed that TSPYL5 could competitively bind to the N-terminal domain of deubiquitylase USP7 in conjunction with p53 and reduce the protective effects of USP7 on p53, resulting in ubiquitin mediated degradation of p53, and that the co-transfection of TSPY1 and TSPYL5 enhanced this effect."
