The ability of elongating RNA polymerase II (RNAPII) to regulate the nucleosome barrier is poorly understood because we do not know enough about the involved factors and we lack a conceptual framework to model this process. Our group recently identified the conserved Fun30/SMARCAD1 family chromatin-remodeling factor, Fun30, as being critical for relieving the nucleosome barrier during RNAPII-mediated elongation, and proposed a model illustrating how Fun30 may contribute to nucleosome disassembly during RNAPII-mediated elongation. Here, we present a model that describes nucleosome dynamics during RNAPII-mediated elongation in mathematical terms and addresses the involvement of Fun30 in this process.
由于我们对相关因子了解不足,且缺乏对这一过程进行建模的概念框架,所以对于延伸中的RNA聚合酶II(RNAPII)调节核小体屏障的能力知之甚少。我们团队最近鉴定出保守的Fun30/SMARCAD1家族染色质重塑因子Fun30,它对于在RNAPII介导的延伸过程中解除核小体屏障至关重要,并提出了一个模型来说明Fun30在RNAPII介导的延伸过程中如何促进核小体解聚。在此,我们提出一个以数学术语描述RNAPII介导的延伸过程中核小体动态变化的模型,并探讨了Fun30在此过程中的作用。
