Evolution Via Gene Duplication And Alternative Splicing In The Eukaryotic Ski7 And Hbs1 Genes, Alexandra Marshall
Dissertations & Theses (Open Access)
Gene duplication and alternative splicing are both recognized as important drivers of proteomic diversity and innovation during evolution, but the evolutionary changes over long periods of time or the interrelations of the two processes has not been extensively studied. Here I study these phenomena for the SKI7 and HBS1 gene pair. These Saccharomyces cerevisiae genes were created as part of a whole genome duplication (WGD) event and have since functionally diverged. Although both genes function in mRNA surveillance pathways, the two genes act on different RNAs and have different effects on the target mRNAs. Ski7 brings the Ski complex and …
