Background

Chromodomain-helicase-DNA-binding domain (CHD) proteins have been identified in a variety of organisms (1,2). This family of nine proteins is divided into three separate subfamilies: subfamily I (CHD1 and CHD2), subfamily II (CHD3 and CHD4), and subfamily III (CHD5, CHD6, CHD7, CHD8, CHD9). All CHD proteins contain two tandem amino-terminal chromodomains, a SWI/SNF-related ATPase domain, and a carboxy-terminal DNA-binding domain (1,2). The chromodomains facilitate binding to methylated lysine residues of histone proteins and confer interactions with specific regions of chromatin. The SWI/SNF-related ATPase domain utilizes energy from ATP hydrolysis to modify chromatin structure. CHD proteins are often found in large, multiprotein complexes with their transcriptional activation or repression activity governed by other proteins within the complex. CHD3 (also known as Mi2-α) and CHD4 (also known as Mi2-β) are central components of the nucleosome remodeling and histone deacetylase (NuRD) transcriptional repressor complex, which also contains HDAC1, HDAC2, RBAP48, RBAP46, MTA1, MTA2, MTA3, and MBD3 (3-8). Both CHD3 and CHD4 contain two plant homeodomain (PHD) zinc finger domains that bind directly to HDAC1 and HDAC2.

染色质解旋酶DNA结合域(CHD)蛋白已经在各种生物组织中得到确认分析(1,2)。该蛋白家族有九个蛋白,被分成三个亚家族:亚家族I(CHD1和CHD2)、亚家族II(CHD3和CHD4)、亚家族III(CHD5,CHD6,CHD7,CHD8,CHD9)。所有的CHD蛋白都具有串联的两个N端染色质结构域,一个SWI/SNF相关的ATP酶结构域和一个C端的DNA结合结构域(1,2)。N端的染色质结构域有助于结合组蛋白上甲基化的赖氨酸残基,加强染色质特殊区域的相互作用。SWI/SNF相关的ATP酶结构域可以利用ATP水解的能量对染色质结构进行改造。CHD蛋白通常是在一些大的多蛋白复合物中存在,CHD蛋白的转录激活或者活性抑制受这些大的多蛋白复合物中其他蛋白影响。CHD3(又称Mi2-α)和CHD4 (也被称为Mi2-β)是核小体重塑和组蛋白脱乙酰化酶(NuRD)转录抑制复合物的核心组成,该复合物也含有HDAC1, HDAC2, RBAP48, RBAP46, MTA1, MTA2, MTA3, 和 MBD3 (3-8)。CHD3和CHD4含有植物同源的(PHD)锌指结构域,直接与HDAC1和HDAC2相互作用。
