OTUB1 activates FOXM1. 7 / 11
| 1 6

eidos
"Mechanistically , knockdown of OTUB1 down-regulated FOXM1 expression by promoting its ubiquitination ."

reach
"We found that LINC00857 acts as a protein scaffold by promoting the interaction between OTU domain-containing ubiquitin aldehyde-binding protein 1 (OTUB1) and FOXM1, which inhibited FOXM1 degradation [MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"The fact that OTUB1 specifically targets FOXM1 also supports the fact that FOXM1 is ubiquitinated by K48-linkage chains."

reach
"OTUB1 enhances FOXM1 stability in response to epirubicin treatment."

reach
"Our data show that WT OTUB1, but not the OTUB1 (C91S) catalytic dead mutant, can enhance the stability of FOXM1 in response to epirubicin in MCF-7 cells, suggesting that the deubiquitinase activity is required for the degradation of FOXM1."

reach
"This finding was interesting as OTUB1 inhibits the degradation of FOXM1 transcription factor, typically upregulated and overexpressed in aggressive therapy resistant breast cancer."

reach
"OTUB1 positively regulates FOXM1, a transcription factor that promotes Snail transcription."
