Background

HELLS, or LSH1, is a lymphoid-specific helicase thought to be involved in cellular proliferation and leukemogenesis (1,2). It is believed to be a chromatin remodeler and is required for DNMT1-mediated methylation maintenance and DNMT3A/DNMT3B-mediated de novo methylation. The role of HELLS in methylation maintenance was thought to be largely confined to repetitive DNA sequences, including major and minor satellite sequences, rather than single copy genes (3,4); recent evidence suggests a role in genome-wide cysteine methylation at non-repeat sequences (5). De novo methylation maintenance is associated with silencing of specific genes, some known to be involved in pluripotency and lineage commitment (6,7).

HELLS或LSH1是一个淋巴特异性解旋酶,它被认为涉及细胞内增殖和起发白血病(1,2)。它被认为是一个染色质重塑蛋白,并且对于DNMT1介导甲基化维护和DNMT3A/DNMT3B介导重新甲基化是需要的。HELLS在甲基化维护中的作用被认为是最大程度限制DNA重复序列,包括主要的和次要的卫星序列,而不是单一复制基因(3,4);最近研究认为在非重复序列中基因组范围内半胱氨酸甲基化的功能(5)。重新甲基化的维持是与特异性基因的沉默有关,一些认为是涉及多潜能和谱系提交(6,7)。
