Abstract

In this report the phenotypic effects of systematic site-directed mutations in the fission yeast RNA pol II carboxy terminal domain (CTD) are investigated. Remarkably, we find that alterations in CTD structure and/or phosphorylation result in distinct phenotypic changes related to morphogenetic control. A hypothesis based upon the concepts of "informational entropy" and "algorithmic transformation" is developed to explicate/rationalize these results.

摘要

在本报告中,我们研究了裂殖酵母RNA聚合酶II羧基末端结构域(CTD)中系统性定点突变的表型效应。值得注意的是,我们发现CTD结构和/或磷酸化的改变会导致与形态发生控制相关的明显表型变化。基于“信息熵”和“算法转换”概念,我们提出了一个假设来解释/合理化这些结果。
