reach
"USP8 (also known as UBPY) deubiquitylates EGFR on early endosomes, rescuing EGFR from degradation 107, 108 ."

reach
"Before incorporation into MVBs, the EGFR is deubiquitinated by Usp8."

reach
"Based on these studies, we propose a model whereby the concerted recruitment of CHMP4B and UBPY to HD-PTP and the engagement of UBPY by STAM2 displaces ESCRT-0 from HD-PTP, deubiquitinates EGFR, and releases ESCRT-0 from cargo in favor of ESCRT-III."

reach
"Some studies showed that AMSH [31] and UBPY [32, 33] prevent EGFR down-regulation by deubiquitinating EGFR."

reach
"While AMSH is required for sorting of EGFR into MVEs and degradation in lysosomes XREF_BIBR, deubiquitination of EGFR by USP8 protects it from lysosomal degradation XREF_BIBR."

reach
"Gain-of-function mutations in USP8 increase the deubiquitination of EGFR, which inhibits its degradation, leading to the activation of EGFR signaling."

reach
"In addition, it has been reported that the deubiquitinase Usp8 could deubiquitinate Smo to influence Hh signaling activity."

reach
"Although our observations support the notion that USP8 deubiquitinates Smo and prevents localization to early endosomes, we are not suggesting that USP8 play an exclusive role in the inhibition of Smo endocytosis."

reach
"As shown in XREF_FIG, USP8, but not the other DUBs, reduced the ubiquitination of Myc-Smo."

reach
"In addition, it has been reported that the deubiquitinase Usp8 could deubiquitinate Smo to influence Hh signaling activity (Li et al., 2012; Xia et al., 2012)."

reach
"Hh promotes the formation of a Smo and USP8 complex, and USP8 further promotes the accumulation of Smo at the cell surface and prevents localization to the early endosomes by deubiquitinating Smo, leading to increased Hh signaling activity."

reach
"Inactivation of the ubiquitin activating enzyme-Uba1 promotes Smo accumulation on the cell surface and Hh signaling activation, and USP8 decreases Smo ubiquitination to promote its cell surface accumulation in the absence or presence of Hh."

reach
"Using an in vivo RNAi screen, we identified ubiquitin specific protease 8 (USP8) as a deubiquitinase that down-regulates Smo ubiquitination."

reach
"In addition, we provide evidence that the non visual beta-arrestin Krz acts in parallel with Smo ubiquitination to promote its internalization and that Smo ubiquitination is antagonized by the deubiquitinating enzyme UBPY."

reach
"However, we found that UBPY decreases Smo ubiquitination regardless of the Hh signaling states and that the association between UBPY and Smo is not significantly affected by either Hh stimulation or Smo phosphorylation, suggesting that Smo deubiquitination by UBPY is unlikely to be a major mechanism by which Hh inhibits Smo ubiquitination, although we can not rule out the possibility that Hh regulates UBPY binding to Smo in a subtle way that escaped the detection by our coimmunoprecipitation assay."
Modified USP8 leads to the deubiquitination of SMO. 4 / 4

reach
"Overexpression of Flag-USP8 in S2 cells reduced Smo ubiquitination (XREF_FIG, lane 3, top panel), whereas knockdown of USP8 by RNAi enhanced the levels of ubiquitinated Smo (XREF_FIG, lane 2, top panel), which was consistent with the data from the screen."

"Mechanistically, USP8 directly removes non-classical K63-linked ubiquitin chains from EPG5 at Lysine 252, leading to enhanced interaction between EPG5 and LC3."

reach
"We revealed that the deubiquitinase USP8 maintains ESC identity by directly deubiquitinating EPG5 to consolidate the interaction between EPG5 and LC3 and sustain the normal autophagic flux for stemness maintenance (Fig. 6g)."

reach
"Furthermore, we have demonstrated that USP8 deubiquitinates CHMP1B."

reach
"Based on these observations, we propose that CHMP1B is dynamically regulated by ubiquitination in response to EGF and that USP8 triggers CHMP1B deubiquitination possibly favoring its subsequent assembly into a membrane associated ESCRT-III polymer."

reach
"Finally, we observed that the ubiquitination level of endogenous CHMP1B was higher in partially Usp8 silenced cells compared to control cells, strengthening the hypothesis that USP8 deubiquitinates CHMP1B (XREF_FIG)."

reach
"Thus, deubiquitination of CHMP1B by USP8 at the endosomal membrane may favor CHMP1B oligomerization and co-assembly with IST1 in vivo."

reach
"From these observations, we propose that CHMP1B is dynamically regulated by ubiquitination in response to EGF and that USP8 triggers CHMP1B deubiquitination possibly favoring its subsequent assembly into a membrane associated ESCRT-III polymer."
