Areas of Interest

Mission Statement: Our goal is to discover the principles and mechanisms that control expression of genes, with the benefit to society that this knowledge will enhance our understanding of the causes of disease and advance therapeutic strategies to correct deleterious gene expression.

Expertise: Gene regulation, post-transcriptional control of messenger RNA stability, translation and localization by RNA-binding proteins, mRNA untranslated regions, and nucleases. Genetic mechanisms of development, cancer and obesity.

Summary: Our goal is to understand how messenger RNAs are regulated. Regulation of translation, degradation and localization of mRNAs contributes to the enormous dynamic range of protein expression. Misregulation can cause disease, developmental defects, or death. Sequence specific RNA-binding factors, both protein and small RNAs, play a central role in mRNA regulation. Our research focuses on two important classes of regulatory proteins: PUFs and deadenylases

PUF proteins We study PUF proteins, a family of regulators that bind certain mRNAs with exquisite specificity and repress their expression. PUF proteins have diverse biological roles in development, stem cell proliferation, and fertility. PUFs also control neurological processes including motor neuron function, learning and memory formation. Our goals are to identify the mRNAs that PUF proteins regulate and determine the molecular mechanism of repression. To accomplish this, we use a combination of biochemistry, genetics, bioinformatics, transcriptomics, and high throughput assays in multiple organisms including Humans, Drosophila and Yeast. This research has direct impact on genetic mechanisms that control development, neurological function, and cancer.

Deadenylases Ribonucleases play critical roles in regulating mRNAs. Deadenylases are specialized ribonucleases that degrade the poly(Adenosine) tails of mRNAs. Regulation of poly(A) tail length is emerging as a critical control point for translation and mRNA degradation in a wide variety of biological contexts. Indeed, we found that specific deadenylases play a central role in PUF regulation. PUF proteins enhance deadenylation of the mRNAs they bind by directly recruiting the deadenylase enzyme complex.

The versatility of regulation by deadenylation is greatly expanded in higher eukaryotes through diversification of deadenylases. For instance, humans possess twelve deadenylase orthologs. Genetic analysis indicates that each deadenylase controls unique biological functions including cell division and growth, metabolism, development, bone morphogenesis and anti-viral responses. We are exploring the questions: how many active deadenylases are there, do their catalytic activities differ, which mRNAs do they act upon, and how are their activities controlled?
