- Abstract
Nuclear actin and myosin 1 (NM1) are key regulators of gene transcription. Here, we show by biochemical fractionation of nuclear extracts, protein-protein interaction studies and chromatin immunoprecipitation assays that NM1 is part of a multiprotein complex that contains WICH, a chromatin remodelling complex containing WSTF (Williams syndrome transcription factor) and SNF2h. NM1, WSTF and SNF2h were found to be associated with RNA polymerase I (Pol I) and ribosomal RNA genes (rDNA). RNA interference-mediated knockdown of NM1 and WSTF reduced pre-rRNA synthesis in vivo, and antibodies to WSTF inhibited Pol I transcription on pre-assembled chromatin templates but not on naked DNA. The results indicate that NM1 cooperates with WICH to facilitate transcription on chromatin.
