25431208 OTUB1 promoted the metastasis of CRC cell lines.
24763515 After viral infection, HSCARG interacted with tumor necrosis receptor-associated factor 3 (TRAF3) and inhibited its ubiquitination by promoting the recruitment of OTUB1 to TRAF3.

23955022 A second role of OTUB1-E2 interactions is to stimulate OTUB1 cleavage of Lys48 polyubiquitin. This stimulation is regulated by the ratio of charged to uncharged E2 and by the concentration of Lys48-linked polyubiquitin and free ubiquitin.
23524849 These results suggest that OTUB1 regulates NF-kappaB and MAPK signalling pathways and TNF-dependent cell death by modulating c-IAP1 stability.

22124327 Overexpression of Otub1(D88A) or ablation of endogenous Otub1 by siRNA markedly impaired p53 stabilization and activation in response to DNA damage. Together, these results reveal a novel function for Otub1 in regulating p53 stability and activity
20725033 OTUB1, a deubiquitinating enzyme, is an inhibitor of double-strand break-induced chromatin ubiquitination
20553488 Post-translational modifications of OTUB1 suggests a new entry point for manipulating Yersinia interactions with the host.
