SMARCA1 (SNF2L) is one of the two orthologs of the ISWI (imitation switch) ATPases encoded by the mammalian genome (1). The ISWI chromatin remodeling complexes were first identified in Drosophila and have been shown to remodel and alter nucleosome spacing in vitro (2). SMARCA1 is the catalytic subunit of the NURF (nucleosome remodeling factor) and CERF (CECR2-containing remodeling factor) complexes (3-5). The NURF complex plays an important role in neuronal physiology by promoting neurite outgrowth and regulation of Engrailed homeotic genes that are involved in neuronal development in the mid-hindbrain (3). NURF is also thought to be involved in the maturation of T cells from thymocytes by regulating chromatin structure and expression of genes important for T cell development (6). The largest subunit of the NURF complex, BPTF, is required for proper development of mesoderm, endoderm, and ectoderm tissue lineages, suggesting a role for SMARCA1 in the development of the germ layers in mouse embryo (7). Disruption of the CERF complex by deletion of CECR2, an interacting partner of SMARCA1, is associated with the neural tube defect exencephaly, linking the CERF complex with regulation of neurulation (4).

SMARCA1 (SNF2L)是ISWI (imitation switch) ATPases的两个直系同源物之一,其由哺乳动物基因编码(1)。 ISWI染色质重塑复合物首先被鉴定在果蝇中,并且在体外被显示去改造和改变核小体间隔(2)。SMARCA1是NURF(nucleosome remodeling factor)和CERF(CECR2-containing remodeling factor) 复合物的催化亚单位(3-5)。NURF复合物在神经生理学中起到重要作用,通过促进神经突起生长和调节Engrailed同源异型基因,该基因涉及到在中后脑中的神经元的发育(3)。NURF也是被认为是涉及来自胸腺的T细胞成熟,这通过调节染色质结构和T细胞发育的基因表达 (6)。NURF复合物的最大亚基BPTF对于中胚层、内胚层和外胚层组织谱系是需要的,这认为在小鼠胚胎中SMARCA1的功能是促进胚层的发育 (7)。CECR2是一个SMARCA1相互作用的蛋白质,由CECR2的缺失引起的CERF复合物的分解与露脑性神经索缺陷有关联,这联系着与神经胚形成的调节有关的CERF复合物(4)。
