HBZ — JUN

Text-mined interactions from Literome

Matsumoto et al., Oncogene 2005 (Leukemia-Lymphoma, Adult T-Cell) : In the course of investigating HBZ function, we found that HBZ reduced the steady-state levels of c-Jun , and the levels were restored by treatment with a proteasome inhibitor ... Together, this indicates that HBZ promotes c-Jun degradation through a proteasome dependent pathway ... These results suggest dual effects of HBZ on the suppression of AP-1 activity by inhibiting c-Jun function, which may contribute to the dysregulation of cell proliferation
Hivin et al., Nucleic Acids Res 2006 : Like c-Fos, HBZ ( HTLV-I bZIP factor ) is able to interact with c-Jun but differs considerably from c-Fos in its ability to activate AP-1-responsive genes since HBZ rather inhibits transcriptional activity of c-Jun
Isono et al., J Biol Chem 2008 : Although most proteasomal substrates are targeted for degradation via conjugation of polyubiquitin chains, we show that ubiquitination is not required for HBZ mediated proteasomal degradation of c-Jun
Clerc et al., Virology 2009 : In conclusion, we demonstrate that the repression of c-Jun activity in vivo is mainly due to the HBZ-SP1 mediated sequestration of c-Jun to the HBZ-NBs
