STAMBP inhibits EGFR. 6 / 9
| 6

reach
"In contrast, EGF-R internalization is inhibited by AMSH protein."

reach
"Based on siRNA-depletion experiments, AMSH is proposed to negatively regulate EGFR downregulation and consequently to enhance recycling of the receptor ( Bowers et al., 2006 ; McCullough et al., 2004 [MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"Depletion of AMSH, which alters the balance of E3 ligase and DUB activity in the endosomal system, enhances the degradation of EGFR, presumably by inhibiting the removal of ubiquitin from EGFR and thereby preventing its ability to recycle."

reach
"Inhibition of AMSH accelerates EGFR down-regulation suggesting a role in antagonizing ubiquitin dependent sorting of cargo to the lysosome."

reach
"Conversely, AMSH negatively regulates EGFR down-regulation and is proposed to recycle the EGFR at the sorting endosome."

reach
"Short interfering RNA (siRNA) knockdown of AMSH accelerates EGFR down-regulation."
