Uetz Lab Research

Welcome to the Uetz lab at VCU. We are working on proteins, protein function, protein-related bioinformatics and reptile taxonomy. Our main projects and selected publications are listed below. For a complete publication list go to Publications.

Bacterial interactomics

Our group has mapped the interactomes of 4 different microbial species, more than any other lab in the world. These interactomes have provided insights into the molecular organization of unicellular systems and the functions of their proteins.

Protein function, protein complexes, and protein domains

We are interested in protein function, especially the functions of uncharacterized and poorly understood proteins. We use protein-protein interaction studies and other methods to elucidate their function.

Virus and phage interactomics

Viruses and phage are excellent models to study protein interaction networksand protein function because they are small and have loads of uncharacterized proteins. We have studied both human viruses and phage of various bacteria, including E. coli, Mycobacteria, and Streptococcus. We have recently started to study bacteriophage of Bacillus in collaboration with Drs. Margarita Salas and Allison Johnson.

• Fossum E. et al. (2009) Evolution and divergence of herpesviral protein interaction networks. PloS Pathogens 5 (9): 00570

Bioinformatics of protein networks

In addition to generating interactome data, we also analyze the resulting networks with a variety of bioinformatics methods. Eventually the goal is to understand both the organisms but also individual proteins and protein domains.

Biodiversity: Reptile taxonomy and genomics

There are not only millions of proteins but also millions of species. Our contribution to biodiversity research is the Reptile Database and its integration with other data sources, including genomics and ecological data.
