Synthetically engineered rpb1 alleles altering RNA polymerase II carboxy terminal domain phosphorylation induce discrete morphogenetic defects in Schizosaccharomyces pombe.
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.
