CHD1 controls H3.3 incorporation in adult brain chromatin to maintain metabolic homeostasis and normal lifespan.
Title: CHD1 controls H3.3 incorporation in adult brain chromatin to maintain metabolic homeostasis and normal lifespan.
An effect of Chd1 null mutation can be increased by deficiency of one of the genes, encoding variant histone H3.3, His 3.3 B, suggesting that the role of CHD1 in the control of male X chromosome organization can be mediated by CHD1 activity in H3.3 histone deposition and exchange.
Title: THE INFLUENCE OF THE Chd1 CHROMATIN ASSEMBLY AND REMODELING FACTOR MUTATIONS ON DROSOPHILA POLYTHENE CHROMOSOME ORGANIZATION.
The Drosophila melanogaster CHD1 chromatin remodeling factor modulates global chromosome structure and counteracts HP1a and H3K9me2.
Title: The Drosophila melanogaster CHD1 chromatin remodeling factor modulates global chromosome structure and counteracts HP1a and H3K9me2.
Intestinal resistance against infection by P. aeruginosa is linked to maintaining proper balance of gut-microbe interactions and the chromatin remodeler CHD1 is involved in regulating this aspect.
Title: CHD1 contributes to intestinal resistance against infection by P. aeruginosa in Drosophila melanogaster.
our results emphasize a role for Chd1 in histone replacement in both budding yeast and Drosophila melanogaster, and surprisingly they show that the major effects of Chd1 on turnover occur at the 3' ends of genes.
Title: A key role for Chd1 in histone H3 dynamics at the 3' ends of long genes in yeast.
These results clarify the roles of chromatin remodelers in transcription and provide novel insights into CHD1 function.
Title: Investigations of CHD1 function in transcription and development of Drosophila melanogaster.
findings establish CHD1 as a major factor in replacement histone metabolism in the nucleus and reveal a critical role for CHD1 in the earliest developmental instances of genome-scale, replication-independent nucleosome assembly.
Title: CHD1 motor protein is required for deposition of histone variant H3.3 into chromatin in vivo.
results suggest a role for CHD1 in the assembly of active chromatin and a function of ACF in the assembly of repressive chromatin
