Citation | Journal: Proc Natl Acad Sci U S A / Year: 2022Title: Multistate structures of the MLL1-WRAD complex bound to H2B-ubiquitinated nucleosome. Authors: Sanim Rahman / Niklas A Hoffmann / Evan J Worden / Marissa L Smith / Kevin E W Namitz / Bruce A Knutson / Michael S Cosgrove / Cynthia Wolberger / ![]() Abstract: The human Mixed Lineage Leukemia-1 (MLL1) complex methylates histone H3K4 to promote transcription and is stimulated by monoubiquitination of histone H2B. Recent structures of the MLL1-WRAD core ...The human Mixed Lineage Leukemia-1 (MLL1) complex methylates histone H3K4 to promote transcription and is stimulated by monoubiquitination of histone H2B. Recent structures of the MLL1-WRAD core complex, which comprises the MLL1 methyltransferase, DR5, bBp5, sh2L, and PY-30, have revealed variability in the docking of MLL1-WRAD on nucleosomes. In addition, portions of the Ash2L structure and the position of DPY30 remain ambiguous. We used an integrated approach combining cryoelectron microscopy (cryo-EM) and mass spectrometry cross-linking to determine a structure of the MLL1-WRAD complex bound to ubiquitinated nucleosomes. The resulting model contains the Ash2L intrinsically disordered region (IDR), SPRY insertion region, Sdc1-DPY30 interacting region (SDI-motif), and the DPY30 dimer. We also resolved three additional states of MLL1-WRAD lacking one or more subunits, which may reflect different steps in the assembly of MLL1-WRAD. The docking of subunits in all four states differs from structures of MLL1-WRAD bound to unmodified nucleosomes, suggesting that H2B-ubiquitin favors assembly of the active complex. Our results provide a more complete picture of MLL1-WRAD and the role of ubiquitin in promoting formation of the active methyltransferase complex. | ||||||
