Research Interests

My lab studies nuclear encoded mitochondrial genes. We focus on their regulation and function in energy metabolism and the pathologies associated with their dysfunction. Some proteins of the electron transport chain are encoded by mitochondrial DNA and some by nuclear DNA. We have largely focused on the nuclear-encoded subunits, particularly those of cytochrome c oxidase (CcO), the terminal enzyme complex of the respiratory chain.

A recent interest has been a lung and trachea-specific isoform of subunit IV that we discovered, CcO4-2. We are currently examining the lung-specific isoform in particular detail, both by studying its transcriptional regulation, especially by hypoxia, to understand its signaling circuitry and interaction with other cellular components, and by examining a recently created mouse null mutant.

A specific area of emphasis is preterm birth and its relation to metabolic dysfunction in energy metabolism.

We are also interested in their molecular evolution; we have developed the picture that cytochrome c and subunits of complex III and of CcO that interact with it have undergone a period of accelerated evolution suggestive of positive selection during primate ancestry. We have speculated that this accelerated evolution was ultimately driven by the energetic needs of an enlarged neocortex. A portion of this acceleration has had the effect of remodeling the docking site of cytochrome c on CcO so as to change the binding interaction from a predominantly electrostatic one to a predominantly hydrophobic one. We are now seeking to characterize biochemically resulting modifications in electron transport. More generally, we are interested in the genetic changes that have made us uniquely human, and in the relation between rapidly evolving genes and human disease.
