在人类转录调控中,dna序列特异性因子可以与协调多种染色质修饰酶相互作用的中介体相关联。其中一种中间物是HCFC1(也称为HCF-1)。HCFC1首次在单纯疱疹病毒转录中被发现,在细胞转录调控中的作用尚不明确。我们在这里表明,在HeLa细胞中,HCFC1被观察到与5400个普遍活跃的cpg岛启动子结合。对hcfc1结合位点的DNA序列的检查揭示了与(1)ZNF143和THAP11(也称为Ronin), (2) GABP和(3)YY1序列特异性转录因子结合相关的三个序列基序。随后的分析显示,在5400个HCFC1结合启动子中,约90%的HCFC1与这四种转录因子共定位。这些研究表明,相对较少的转录因子在与HCFC1相关的hela细胞转录调控中起主要作用。
In human transcriptional regulation, DNA-sequence-specific factors can associate with intermediaries that orchestrate interactions with a diverse set of chromatin-modifying enzymes. One such intermediary is HCFC1 (also known as HCF-1). HCFC1, first identified in herpes simplex virus transcription, has a poorly defined role in cellular transcriptional regulation. We show here that, in HeLa cells, HCFC1 is observed bound to 5400 generally active CpG-island promoters. Examination of the DNA sequences underlying the HCFC1-binding sites revealed three sequence motifs associated with the binding of (1) ZNF143 and THAP11 (also known as Ronin), (2) GABP, and (3) YY1 sequence-specific transcription factors. Subsequent analysis revealed colocalization of HCFC1 with these four transcription factors at ∼90% of the 5400 HCFC1-bound promoters. These studies suggest that a relatively small number of transcription factors play a major role in HeLa-cell transcriptional regulation in association with HCFC1.
