Gene activity is mediated by site-specific transcription factors (TFs). Their binding to defined regions in the genome determines the rate at which their target genes are transcribed.
We present a comprehensive computational model of the search process of TF for their genomic target site(s). The computational model considers: the DNA sequence, various TF species and the interaction of the individual molecules with the DNA or between themselves. We also demonstrate a systematic approach how to parametrize the system using available experimental data.
基因活性是由特定的转录因子(TF)介导的。它们与基因组中特定区域的结合决定了其靶基因转录的速度。
我们提出了一个全面的计算模型,用于研究 TF 搜索其基因组靶位点的过程。该计算模型考虑了 DNA 序列、各种 TF 物种以及单个分子与 DNA 或彼此之间的相互作用。我们还展示了一种如何使用现有实验数据对系统进行参数化的系统方法。
