ATP-dependent chromatin remodeling complexes play an essential role in the regulation of nuclear processes such as transcription and DNA replication and repair (1,2). The SWI/SNF chromatin remodeling complex consists of more than 10 subunits and contains a single molecule of either BRM or BRG1 as the ATPase catalytic subunit. The activity of the ATPase subunit disrupts histone-DNA contacts and changes the accessibility of crucial regulatory elements to the chromatin. The additional core and accessory subunits play a scaffolding role to maintain stability and provide surfaces for interaction with various transcription factors and chromatin (2-5). The interactions between SWI/SNF subunits and transcription factors, such as nuclear receptors, p53, Rb, BRCA1, and MyoD, facilitate recruitment of the complex to target genes for regulation of gene activation, cell growth, cell cycle, and differentiation processes (1,6-9).

ATP依赖的染色质重塑复合物,在调节如转录、DNA的复制和修复等细胞核反应起着重要作用(1,2)。SWI/SNF染色质重塑复合物由10多个亚基组成,包含BRM或BRG1任一单分子作为ATP酶催化亚基。ATP酶亚基活性能够破坏组蛋白与DNA的结合,同时改变染色质重要调控元件与染色质的结合。额外的核心和配体亚基起着支架作用,有助于稳定各种转录因子和染色质的相互作用,为其提供作用表面(2-5)。SWI/SNF亚基与各种转录因子如核受体,p53, Rb, BRCA1和MyoD等的相互作用,有利于招募复合物结合目标基因,对基因的激活、细胞生长、细胞周期和分化过程进行调控(1,6-9)。

ARID1A is one of the accessory subunits of the SWI/SNF complex that is an essential part of the esBAF (mouse embryonic stem cell specific SWI/SNF complex). ARID1A is critical for ES cell pluripotency and differentiation into mesoderm-derived cardiomyocytes and adipocytes (10). In addition, ARID1A has been found to be frequently mutated in several cancers such as uterine and ovarian endometrioid carcinoma and ovarian clear cell carcinoma (11-13).
