Biological macromolecules comprise fantastic objects with nearly unlimited activities and potentialities. Their use in biotechnology has already changed several segments of industry including the detergents, paper industries, the food industry (e.g. sugar), and is expected to revolutionize the medical industry.
Our Lab aims to decipher the mechanisms by which those molecules evolve, to understand the molecular basis of their biological functions, and to develop new methods for their engineering, with the aim of developing soft, ecological solutions to existing or emerging society issues.

Microbes and plants synthesize a tremendous diversity of chemical compounds that is unmatched by synthetic methods. We are interested in exploring and utilizing the metabolic machineries of plants and microorganisms to enable the discovery and synthesis of valuable compounds in recombinant microbial hosts. We combine enzyme functions obtained from different sources into new metabolic reactions sequences for desired compounds.

DNA replication is an integral part of the eukaryotic cell cycle, which coordinates the duplication of the entire genome during S phase. At the onset of S phase, origins of DNA replication are activated to "fire". Once DNA synthesis has been initiated, the cell is committed to undergo a complete round of division.

Our objective is to gain an understanding of the molecular and biochemical mechanisms of mammalian DNA double-strand break (DSB) repair. The importance of DNA DSB repair is underscored by the existence of human cancer predisposition diseases, such as Nijmegen chromosome breakage syndrome, ataxia telangiectasia and Fanconi's anemia, which are caused by defects in DNA repair.

Every biological process is regulated by several different control mechanisms. Our research focuses on how the individual mechanisms work and how they are coordinated with each other. We are studying the regulation of the glyoxylate bypass in the bacterium Escherichia coli. We chose this organism because it can be manipulated with a variety of powerful genetic techniques.

Most eucaryotic genes are controlled by developmental, hormonal, tissue-specific, and/or nutritional cues. Insight into these complex regulatory events is fundamental to our understanding of the processes controlling cellular proliferation and oncogenesis, differentiation, and development. The long-term goal of the research in my laboratory focuses on investigating how estrogen and testosterone regulate gene expression, both physiologically and pathologically. To address this, we are investigating the structure and function of the estrogen- and testosterone-responsive ZEB-1 (delta EF1) transcription factor.

Virtually all genes in higher organisms are interrupted by regions of noncoding DNA called introns. These introns must be removed from messenger RNA precursors to allow proper gene expression. The process of pre-mRNA splicing is responsible for accurately identifying introns and catalyzing their excision. A fundamental challenge in modern molecular biology is to understand how the splicing apparatus specifically recognizes and removes introns. Because the splicing machinery is highly conserved throughout evolution, my laboratory approaches this question using the genetic and biochemical tools available uniquely in the yeast Saccharomyces cerevisiae.

The stability of the cellular genome is constantly threatened by a variety of exogenous and endogenous mutagenic agents such as UV light, reactive oxygen species, etc. Cells protect their genome against carcinogenic alterations by using a complex network of “caretaker” proteins that function to maintain the integrity of the cellular chromosomes. Inherited defects in these caretaker genes are the cause of genomic instability syndromes in humans, such as Fanconi Anemia or Bloom syndrome, characterized by a highly elevated risk to develop certain types of cancer. We study these diseases to understand and discover novel mechanisms important to control and suppress cancer susceptibility.

Our objective is to fully define the function of dystrophin in striated muscle to understand how its absence or abnormality leads to the pathologies observed in Duchenne and Becker muscular dystrophies. Our unique approach integrates biochemical and biophysical analyses of the very large dystrophin protein with in vivo assessments of its function in transgenic mouse models of muscular dystrophy.

We are interested in understanding the molecular networks that coordinate nutrient metabolism and cell growth. How cells assess nutrient- or energy states and relay this information into appropriate decisions on growth is poorly understood. Coordinate regulation of nutrient metabolism and cell growth is of fundamental importance, and many human diseases, such as cancer, diabetes, and developmental disorders, are affected by alterations in this process.

We study the metabolism of nicotine and nitrosamines. Nicotine is not a carcinogen, but nitrosamines are potent carcinogens and are believed to be causative agents for a number of human cancers. We are particularly interested in the tobacco specific nitrosamine, NNK. NNK requires cytochrome P450-catalyzed metabolism to exert its carcinogenic potential.

Our research program is broadly directed at assay development for post-translational modifications (PTMs), with a focus on protein phosphorylation by tyrosine kinases. Protein tyrosine kinases play key roles in disease and are particularly important in cancer: mutations in several protein tyrosine kinase genes have been identified as drivers of many tumor types and drugs targeted at inhibiting these enzymes represent ~20% (>$9 billion) of the current oncology market.

Our lab is interested in how cell surface receptors convert signals from extracellular stimuli like mechanical force into a biological response, as dysregulation in a cell’s force-sensing ability can lead to disease. We use X-ray crystallography and other biophysical methods to ask what “mechanosensors” look like in order to understand the range of structures nature uses to sense forces of different magnitudes and in different contexts, and hopefully identify potentially novel therapeutic targets.

We investigate the mechanisms of oxygenases, the enzymes nature uses to catalyze the incorporation of oxygen into biological molecules. Oxygen incorporation reactions are important for a wide variety of reasons, ranging from activation of steroid hormones in humans to the detoxification of compounds in the environment. The oxygenases we study contain a metal which is the key to the chemistry they catalyze.
