COPS5 activates HIF1A. 3 / 8
| 3

reach
"Second, in a manner independent of the CSN holocomplex, CSN5 (or a CSN5 containing small complex) promotes cell proliferation by inducing p27 degradation [22,23] and HIF1-alpha stabilization [41]."

reach
"While Jab1 promotes HIF-1alpha stability and transactivation, p53 degrades HIF-1a and decreases its transactivation."

reach
"However, in contrast to the studies involving MIF regulation of the SCF complex resulting in enhanced degradation and decreased stability of p27 and Cdc25A proteins, MIF and CSN5 regulates HIF-1alpha turnover resulting in enhanced stability and decreased degradation of HIF-1alpha."
