Chromatin remodeling and transcriptional regulation.
Extensive studies in the past few years have begun to demonstrate that chromosome structure plays a critical role in transcriptional regulation. 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. Acetylation of histone lysine residues has been ...
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 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 کاملCoordination of matrix attachment and ATP-dependent chromatin remodeling regulate auxin biosynthesis and Arabidopsis hypocotyl elongation
Hypocotyl elongation is extensively controlled by hormone signaling networks. In particular, auxin metabolism and signaling play key roles in light-dependent hypocotyl growth. The nuclear matrix facilitates organization of DNA within the nucleus, and dynamic interactions between nuclear matrix and DNA are related to gene regulation. Conserved scaffold/matrix attachment regions (S/MARs) are anch...
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 ...
