... theMuvB proteins Lin-37, Lin-52, Lin-54 and chromatin-associated Lin-9 and Lin-53 ⁄ RBBP4 ⁄ RbAp48.Furthermore, A-Myb and B-Myb were present in immunoprecipitations for Lin-9, Lin-37 and Lin-54[90,92]. ... E2F1, -2 and -3. These acti-vating E2Fs cooperate with NF-Y proteins binding toCCAAT-boxes and with Myb proteins associating witha distal Myb site in activating the Cdc2 promoter.Binding of ... which Lin-9 exerts its control [94]. In anotherreport, depletion of Lin-9, Lin-37, Lin-52 or Lin-54 byRNAi also led to a repression of genes, such as cyclinA and cyclin B1, in dividing cells...
