"However, while exploring the relationship between UCH-L1 and p53 ubiquitination, it is important to keep in mind that, despite hypotheses to the contrary [XREF_BIBR, XREF_BIBR], it is unlikely that UCH-L1 directly deubiquitinates or ubiquitinates p53 based on what is known about UCH-L1 structure and function [XREF_BIBR, XREF_BIBR]."

"Our previous work demonstrated that UCHL1 could activate the p14ARF-p53 signaling pathway by deubiquitinating p53 and p14ARF as well as ubiquitinating MDM2, which might be through its two opposing enzyme activities, hydrolase and ligase, further resulting in its tumor suppressive role in NPC tumorigenesis XREF_BIBR, XREF_BIBR."

"As P53 protein is regulated through ubiquitin dependent degradation in tumorigenesis, UCHL1 promotes p53 signaling by deubiquitinating p53 and p14 ARF and ubiquitinating MDM2 for further MDM2 degradation and p53 stabilization, thus involved in NPC pathogenesis as a functional TSG XREF_BIBR."
