Research:

Gene expression is highly regulated to ensure that the correct proteins are made in the right cell at the right time. RNA-binding proteins (RBPs) are central to this regulation, acting at multiple levels to fine-tune genetic output. In the nucleus, RBPs have important roles in regulating the processing of mRNA precursors (pre-mRNA) into the smaller mRNA forms that serve as templates for protein synthesis. In different cell types and in different stages of development, pre-mRNA processing events can be altered to generate ‘alternative’ mRNAs. Alternative pre-mRNA processing is a major mechanism used to diversify gene expression in different cell types, allowing individual genes to yield multiple alternative mRNAs that encode related proteins with distinct functional properties. In addition to changing protein-coding sequences, alternative processing can alter regulatory elements that affect mRNA stability, cellular localization, and translation efficiency –elements that are recognized by specific RBPs.

 

The major goal of my lab is to understand how different RBPs regulate gene expression during mouse spermatogenesis. Research in the lab will combine genetic, bioinformatic, biochemical, and high throughput methods to generate transcriptome-wide maps of RBP-RNA interactions and mRNA regulation in specific spermatogenic cell types (from stem cell to gamete).
