USP4 activates TRAF2. 4 / 4
| 4

reach
"Recently, Xiao et al reported that USP4 targeted TRAF2 and TRAF6 for deubiquitination and inhibited the migration of tumor necrosis factor-alpha (TNF-alpha)-stimulated cancer cells."

reach
"USP4 has also been shown to target TRAF2 and TRAF6 inhibiting nuclear factor-kappaB (NF-kB) signalling and antagonizing lung cancer cell migration XREF_BIBR XREF_BIBR XREF_BIBR, suggesting a context dependent role in cancer."

reach
"However, in breast cancer, USP4 was also recognized as a tumour suppressor for its up-regulatory effect on programmed cell death 4 (PDCD4) to restrain tumour growth.20 Moreover, USP4 was able to target TRAF2 and TRAF6 for deubiquitination and thereafter inhibited TNFalpha induced cancer cell migration.34 In the present study, we proved that USP4 expression was drastically increased in melanoma."

reach
"USP4 has previously been confirmed to target TRAF2 and TRAF6 for deubiquitination and it has been established that USP4 inhibits TNFalpha induced cancer cell migration 35."
