ATP-dependent chromatin remodeling during mammalian development.
Precise gene expression ensures proper stem and progenitor cell differentiation, lineage commitment and organogenesis during mammalian development. ATP-dependent chromatin-remodeling complexes utilize the energy from ATP hydrolysis to reorganize chromatin and, hence, regulate gene expression. These complexes contain diverse subunits that together provide a multitude of functions, from early emb...
متن کاملATP-dependent mobilization of the glucocorticoid receptor during chromatin remodeling.
Chromatin remodeling by the glucocorticoid receptor (GR) is associated with activation of transcription at the mouse mammary tumor virus (MMTV) promoter. We reconstituted this nucleoprotein transition with chromatin assembled on MMTV DNA. The remodeling event was ATP dependent and required either a nuclear extract from HeLa cells or purified human Swi/Snf. Through the use of a direct interactio...
متن کاملChromatin remodeling by ATP-dependent molecular machines.
The eukaryotic genome is packaged into a periodic nucleoprotein structure termed chromatin. The repeating unit of chromatin, the nucleosome, consists of DNA that is wound nearly two times around an octamer of histone proteins. To facilitate DNA-directed processes in chromatin, it is often necessary to rearrange or to mobilize the nucleosomes. This remodeling of the nucleosomes is achieved by th...
متن کاملATP-dependent chromatin assembly is functionally distinct from chromatin remodeling
Chromatin assembly involves the combined action of ATP-dependent motor proteins and histone chaperones. Because motor proteins in chromatin assembly also function as chromatin remodeling factors, we investigated the relationship between ATP-driven chromatin assembly and chromatin remodeling in the generation of periodic nucleosome arrays. We found that chromatin remodeling-defective Chd1 motor ...
متن کاملATP-dependent remodeling and acetylation as regulators of chromatin fluidity.
It has become widely accepted that modification of nucleosome structure is an important regulatory mechanism. The hypothesis that the acetylation of histones is involved in regulation was first formed over thirty years ago by Allfrey and colleagues (Allfrey et al. 1964). Subsequent genetic studies suggested that complexes that utilize ATP hydrolysis to alter chromatin structure might also play ...
