"The RNAi of UCHL5 or USP14 alone does not affect cell growth and proteasome composition but accelerates cellular protein degradation; however, RNAi of both UCHL5 and USP14 can inhibit cellular protein degradation."

reach
"Importantly, whereas knockdown of POH1 interferes with the proteasome assembly, depletion of either USP14 or UCH37 alone does not affect or even slightly enhances protein degradation rates."

reach
"In contrast, RNAi of either UCHL5 or USP14 alone did not affect cell growth, proteasome structure, or proteolytic capacity, but increased the rate of protein degradation."

reach
"Interestingly, b-AP15, a dual inhibitor of Usp14 and Uch37, was shown to prevent protein degradation and inhibit tumor progression in acute myeloid leukemia models [222]."

reach
"In contrast, RNAi of Uch37 or Usp14 had no detectable effect on cell growth, proteasome structure or proteolytic capacity, but accelerated cellular protein degradation."

reach
"Similarly, the target protein β-catenin is down-regulated, indicating that UCHL5 is likely to inhibit protein degradation through the classical deubiquitination pathway."

reach
"It is believed that Uch37/UCHL5 suppresses protein degradation by shortening the chains of inappropriately or poorly modified substrates ( Lam et al., 1997; Koulich et al., 2008 )."

reach
"It has been shown that UCHL5 controls proteasome function and inhibition of UCHL5 promotes protein degradation in autophagy XREF_BIBR."

reach
"RNAi of either Uch37 or USP14 (the mammalian homologue of yeast Ubp6) accelerates protein degradation."
