Role of Chemical Modifications in RNA Binding Protein and mRNA Processing

Our lab is interested in understanding how chemical modifications in RNA binding proteins play a role in regulating alternative splicing of premature messenger RNA transcripts and in turn, tissue specific gene expression patterns. We use the polypyrimidine tract binding protein family as a model system to carry out our studies. Two main research areas in the lab are to 1) understand the role of phosphate modifications and 2) the role of acetyl modifications in RNA binding protein function.  We use a combination of molecular biology, biochemistry and cell biology techniques to carry out our studies.
