Research Summary
We are interested in links between in transcription and splicing, as well as the role of cellular subcompartments in RNA biogenesis. We use imaging, techniques that capture RNA-protein interactions, and next generation sequencing as major tools. We study these phenomena in yeast (fission and budding), zebrafish and mammalian tissue culture cells.
Specialized Terms: pre-mRNA splicing, transcription, gene architecture, SR proteins, cap-binding complex, RNA-protein interactions, Cajal bodies, organization of the cell nucleus, zebrafish embryogenesis.

Research Image
Higher order organization and functional links among gene expression machineries.
Illustration of the nucleus and cytoplasm of a eukaryotic cell containing nonmembrane-bound cellular bodies, such as nucleoli, Cajal bodies, the histone locus bodies, and P-bodies. Cellular bodies promote molecular interactions by increasing the local concentration of factors. They are often linked to transcription of particular genes (nucleolus: rDNA genes; CB: snRNA genes; histone body locus: histone genes). Similarly, individual machines are rich in RNA polymerase, spliceosomes, RNA-binding proteins and other factors that communicate with one another during gene regulation.
