  sub:_5 prov:value "Phosphorylation of TIF1beta/Ser473 coincides with the induction of cell cycle gene cyclin A2 at the S-phase. Interestingly, chromatin immunoprecipitation demonstrated that the promoter of cyclin A2 gene is occupied by TIF1beta and that such occupancy is inversely correlated with Ser473 phosphorylation. Additionally, when HP1beta was co-expressed with TIF1beta/S473A, but not TIF1beta/S473E, the colocalization of TIF1beta/S473A and HP1beta to the promoters of Cdc2 and Cdc25A was enhanced. Non-phosphorylated TIF1beta/Ser473 allowed greater TIF1beta association with the regulatory regions and the consequent repression of these genes." ;
