“…10 In our recent publication, we proposed that the MYB3R activators and repressors act in coordination rather than in competition, and that repressors are active outside of the G2/M in the cell cycle and in developmental postmitotic states, when the MYB3R activators are inactive. 10 In addition, we showed that MYB3R activators and repressors are present in distinct multiprotein complexes that also contain RBR and specific E2F isoforms. 10,11 These complexes resemble dREAM (Drosophila RBF, E2F2, and Myb) or MMB (Myb-MuvB) complexes in fly, 12,13 and DREAM (DP, RB-like E2F, and MuvB) complex or LINC (LIN complex) in human, 14,15 raising a possibility that MYB3R complexes are plant version of the evolutionarily conserved Keywords: Arabidopsis, cell cycle, cell division, Myb, multiprotein complex, transcription factor *Correspondence to: Masaki Ito; Email: masakito@agr.nagoya-u.ac.jp complexes that control cell cycle-regulated transcription.…”
