Research Abstract
Our laboratory studies retroviruslike elements using the budding yeast (Saccharomyces cerevisiae) retrotransposon Ty3. Retrotransposons make up almost half of the human genome but their regulation and impact on genomic function is not yet well understood; we study Ty3 as a model for understanding both retrotransposons and also retroviruses. Ty3 studies have elucidated the roles of virus structural protein in capsid assembly, roles of nucleoporins in nuclear entry and roles of transcription factors in integration specificity. We are currently focused on how RNA processing proteins help to localize and package the genomic RNA into particles. In addition, the laboratory is working to elucidate the genomic features which affect integration into chromosomal target sites. The laboratory uses a combination of molecular genetics, biochemistry and next generation sequencing to address these questions.
We are using nonconventional yeast to bioengineer metabolism to allow the biosustainable production of high-value chemicals. We developed a unique series of plasmids to allow combinatorial expression of genes for pathway engineering in Saccharomyces cerevisiae. However, S. cerevisiae is fermentative which restricts some of the metabolic studies that it supports. We therefore also study a yeast, Yarrowia lipolytica, which has aerobic metabolism more similar to that of humans than that of S. cerevisiae. Y lipolytica stores excess carbon as lipid rather than polysaccharide. We sequenced, assembled and annotated a reference genome for the industrial CLIB89 strain of this yeast. Recently we completed transposon saturation mutagenesis of this strain in order to identify essential genes and to enable screening for conditionally essential genes. This approach is generally applicable to the development of new fungal systems in order to exploit their diverse metabolism for production of important chemicals.
