USP14 inhibits BECN1. 5 / 6
| 5

reach
"Recently, USP14 was found to directly interact with and inhibit the critical autophagy protein BECN1 in a proteasomal independent manner 66."

reach
"Here, USP14 negatively regulated autophagy in a Beclin-1- and Akt-dependent manner."

reach
"Nevertheless, the precise molecular mechanism by which USP14 suppresses Beclin 1 remains unclear."

reach
"Although the role of USP14 can not be completely ruled out as a proteasome associated DUB enzyme that can affect the expression of TRAF6, these results suggest that USP14 inhibits the interaction of Beclin 1 to TRAF6 through the competitive interaction to TRAF6 with Beclin 1."

reach
"According to this observation, it was shown that USP14 suppresses the activity of Beclin1 complex and induction of autophagy by interacting with and controlling K63- rather than K48 linked ubiquitin chains of Beclin1 [XREF_BIBR]."
