The CXXC finger protein 1 (CXXC1, CGBP, CFP1) is a key subunit of the human SET1 histone methyltransferase complex (1,2) that methylates histone H3 at Lys4 to create a mark of transcriptionally active promoters (3,4). CXXC1 is enriched at CpG islands where it selectively binds non-methylated CpG motifs to provide a link between global H3K4 methylation and CpG islands (5). Research studies have revealed a role for CXXC1 in the maintenance of cytosine methylation through direct interaction with DNMT1 (6-9). The epigenetic functions of CXXC1 are critical for normal embryonic development. Targeted deletion of the murine Cxxc1 gene results in early embryonic lethality while Cxxc1-null embryonic stem (ES) cells exhibit increased apoptosis and fail to undergo differentiation in vitro following withdrawal of leukemia inhibitory factor LIF (6).

CXXC finger protein 1 (CXXC1, CGBP, CFP1) 是人SET1 组蛋白甲基转移酶复合体的一个关键业绩(1,2),该复合体能够甲基化组蛋白H3的Lys4位点从而产生一个转录激活启动子的标志(3,4)。CXXC1在CpG 岛含量丰富,在这里其可以选择性的与非甲基化 CpG motif 结合从而在global H3K4 甲基化与CpG岛建立连接(5)。研究揭示了CXXC1的一个功能,就是通过与DNMT1的直接相互作用从而维持胞嘧啶甲基化(6-9)。CXXC1表观遗传功能对于正常的胚胎发育是至关重要的。定点敲除小鼠的Cxxc1基因会导致早期胚胎致死性,而无Cxxc1基因的胚胎干细胞会呈现出更快的凋亡,并且在去除leukemia inhibitory factor LIF后无法在体外进行分化(6)。
