USP4 deubiquitinates HUWE1. 10 / 10
1 | 9

reach
"USP2 deubiquitinates both MDM2 and MDMX [XREF_BIBR, XREF_BIBR] whereas USP4 deubiquitinates ARF-BP1 [XREF_BIBR], another ubiquitin ligase for p53, thus indirectly destabilizing p53 and inhibiting its function."

reach
"USP4 also interacts directly with and deubiquitinates ARF-BP1, leading to the stabilization of ARF-BP1 and subsequent reduction of p53 levels."

reach
"Recently, ARF-BP1 was reported to specifically target HDAC2 for ubiquitination and degradation and USP4 deubiquitinates and stabilizes ARF-BP1."

reach
"USP4 interacts directly with and deubiquitinates ARF-BP1, leading to the stabilization of ARF-BP1 and subsequent reduction of p53 levels."

reach
"For example, USP4 interacts directly with and deubiquitinates ARF binding protein 1 (ARF-BP1), leading to the stabilization of ARF-BP1 and subsequent reduction of p53 levels."

reach
"USP4 has been recently described as a key regulator of p53 stability: USP4 interacts directly and deubiquitylates the E3 HUWE1 (ARF-BP1; MULE), resulting in reduced p53 levels [86]."

"USP4 inhibits p53 through deubiquitinating and stabilizing ARF-BP1."

reach
"Furthermore, USP4 interacts directly with and deubiquitinates ARF-BP1, leading to the stabilization of ARF-BP1 and subsequent reduction of p53 levels [XREF_BIBR]."

reach
"Nonetheless, USP4 might deubiquitinate and stabilize both ARF-BP1 and its substrate HDAC2."

reach
"USP4 interacts directly with and deubiquitinates ADP-ribosylatibon factor binding protein 1 (ARFBP1), which results in the stabilization of ARF-BP1 and the subsequent reduction of p53 levels."
