Cjoc42 is a compound capable of binding to gankyrin. Cjoc42 inhibits gankyrin activity in a dose-dependent manner. Cjoc42 prevents the decrease in p53 protein levels normally associated with high amounts of gankyrin. Cjoc42 restores p53-dependent transcription and sensitivity to DNA damage[1].
cjoc42 (0.5, 1, and 5 μM; 48 hours) dose-dependently restores p53 levels (comparable to mock transfected cells) and inhibits gankyrin-induced lowering of p53 levels in cells[1].cjoc42 (0.1, 1, and 10 μM; 24 hours) alone shows no dose-dependent change in cell viability[1].
