Cyclin G: a regulator of the p53-Mdm2 network

Dev Cell. 2002 May;2(5):518-9. doi: 10.1016/s1534-5807(02)00182-x.


A recent study published in the April issue of Molecular Cell has shown that cyclin G, a p53 target, is a regulatory component of the active PP2A holoenzyme, which activates Mdm2 through dephosphorylation. These findings suggest that cyclin G is a key regulator of the p53-Mdm2 network.
