OTUB1 inhibits FOXM1. 2 / 7
| 2

reach
"Importantly, knockdown of OTUB1 by siRNA resulted in an increase in turnover of FOXM1 in MCF-7 cells treated with the protein synthesis inhibitor cycloheximide, whereas overexpression of WT OTUB1, but not the OTUB1 (C91S) mutant, significantly enhances the half-life of FOXM1."

reach
"Together, these results suggest that the suppression of FOXM1 degradation by OTUB1 in response to epirubcin requires its deubiquitinating catalytic activity, further confirming that FOXM1 is a novel target of the deubiquitinase OTUB1."
