染色质结构,特别是开放或可接近的染色质位点调节转录因子结合,以确定细胞类型特异性基因表达。两项新的研究发现,SWI/SNF复合物重塑需要持续使用化学和遗传方法来维持开放的染色质,这些方法可以急性抑制或降解BRG 1/BRM ATP酶亚基,导致转录因子结合丧失和基因表达改变。
Chromatin structure and specifically sites of open or accessible chromatin regulate transcription factor binding to determine cell type-specific gene expression. Two new studies find that there is a constant requirement for SWI/SNF complex remodeling to maintain open chromatin using chemical and genetic methods that acutely inhibit or degrade the BRG1/BRM ATPase subunits, leading to loss in transcription factor binding and altered gene expression.
