Promoter-specific trans-activation and inhibition mediated by JunB.

Cancer research - 15 Aug 1993

Hsu J C, Cressman D E, Taub R

Abstract excerpt

Nuclear levels of c-Jun, JunB, c-Fos, and LRF-1 (liver regeneration factor) are high for a large fraction of the G1 phase in regenerating liver and mitogen-stimulated hepatic cells. Previously, JunB was regarded as a less potent transcriptional activator than c-Jun that could also function as a repressor. However, we found that, like c-Jun, JunB alone or LRF-1/JunB strongly transactivates a cAMP-responsive...
