USP19 deubiquitinates BECN1. 8 / 9
1 | 8

reach
"Ultimately, we identified that SIAH1-mediated degradation of USP19 reversed USP19-mediated deubiquitination of MAVS, Beclin1, TRAF3, and TRIF, resulting in the activation of antiviral immune responses."

reach
"Deubiquitinase ubiquitin-specific protein 19 (USP19) is known to be involved in deubiquitinating Beclin1, TRAF3, and TRIF for downregulation of the type I IFN signaling."

reach
"USP19 modulates autophagy and antiviral immune responses by deubiquitinating Beclin-1."

reach
"USP19 can also deubiquitinate and stabilize Beclin 1 (BECN1), thereby promoting autophagy [65] ."

reach
"USP19, which catalyzes the hydrolysis of ubiquitin from its ubiquitin-conjugated protein substrates, is widely expressed in a variety of tissues, including liver, small intestine, and colon ( Combaret[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

"USP19 modulates autophagy and antiviral immune responses by deubiquitinating Beclin-1."

reach
"Conversely, reversal of Beclin1 ubiquitylation by the DUB protein USP19 stabilized the protein under starvation conditions and promoted autophagy."

"However, the substrate(s) that mediate these effects of USP19 remain unknown.A recent report has shown that USP19 can deubiquitinate Beclin-1 and protect it from degradation in cultured non-muscle cel[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"
