The role of nucleosomes is a very important topic of research. It is known that nucleosomes interfere with the binding of transcription factors to DNA, therefore they can control transcription and replication. With the help of an in vitro experiment using yeast, it was discovered that RSC is required for nucleosome remodeling. There is evidence that RSC does not remodel the nucleosomes on its own; it uses information from enzymes to help position nucleosomes. WebOrganization of the lncRNA-dependent omega speckle in Drosophila also depends on the chromatin remodeling complex. These findings raise the possibility that a common mechanism controls the formation of lncRNA-dependent nuclear body architecture. ... Considering that paraspeckle formation is initiated co-transcriptionally on the NEAT1 …

WebEukaryotic chromatin is kept flexible and dynamic to respond to environmental, metabolic, and developmental cues through the action of a family of so-called “nucleosome remodeling” ATPases. Consistent with their helicase ancestry, these enzymes experience conformation changes as they bind and hydrolyze ATP. WebAug 4, 1999 · Two highly conserved mechanisms for altering chromosome structure have been identified: 1) post-translational modification of histones and 2) adenosine triphosphate (ATP)-dependent chromosome remodeling.
