COPS5 activates JUN. 12 / 15
| 1 11

reach
"When transfected into HeLa cells, p38 (JAB1) potentiates the transcriptional activity of c-Jun, but co-transfection with rLHR prevents this effect."

trips
"Jab1 co-activation of c-Jun is abrogated by the serine 10-phosphorylated form of p27Kip1."

reach
"In addition, VDUP1 inhibited JAB1 mediated activator protein-1 activation and cell proliferation."

reach
"Jab1 is a coactivator of c-Jun that enhances the transcriptional function of c-Jun."

reach
"Furthermore, Jab1 mediated PAR-2-induced c-Jun activation, which was followed by increased activation of activator protein-1."

reach
"Overexpression of CSN5 can not rescue c-Jun destabilization in siCSN1."

"Human JAB1 (Jun activation domain binding protein 1) was first described as a coactivator of c-Jun and Jun D. JAB1 enhances the ability of c-Jun and Jun D to activate transcription by stabilizing comp[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"For instance, JAB1 enhances c-Jun transactivation by enhancing binding to their cognate DNA sequences [39,40]."

reach
"COPS5 (official gene symbol of CSN5) is responsible for the deneddylation activity of the COP9 signalosome, and also known as Jab1 to activate c-Jun (Jun-activating and binding protein)."

reach
"CSN5 enhances AP-1-mediated transcriptional activation by stabilizing complexes of the transcription factors c-Jun or JunD [9]."

reach
"Jab1 and CSN5 can specifically stabilize the protein-DNA complexes on the off-rate of c-Jun and JunD with its cognate AP-1 DNA binding sites and potentiate c-Jun transactivation; however, Jab1 and CSN5 does not affect JunB or v-Jun binding [XREF_BIBR]."
