  Laboratory of Nucleic Acids
    The Laboratory of Nucleic Acids studies RNA molecules in their many guises. Led by Dr. Adrian R. Ferr-D'Amare, the lab employs fundamental biophysical approaches to understanding the function of non-coding RNAs, and seeks to leverage this knowledge for the development of new therapeutics and biotechnological tools.

  Research Interests
              Ribonucleic acids (RNA) are remarkable molecules. In addition to serving their classical role as carriers of genetic information, they are also cellular machines that perform enzymatic and regulatory functions previously only ascribed to proteins. Furthermore, since RNA molecules are simultaneously capable of carrying genetic information and functioning as catalysts, they can be subjected to evolutionary selection pressures and may have formed the basis for ancestral life. Finally, RNA’s central role in life suggests that its potential therapeutic value is barely tapped but already clinically validated: approximately 80 percent of antibiotics in use today target a single type of RNA-containing enzyme, the ribosome, and most do so by targeting its non-coding RNA component.

Dr. Ferré-D’Amaré studies RNA molecules in their many guises. His laboratory develops and exploits fundamental biophysical approaches to understanding the function of ribozymes (catalytic RNAs) and the interactions between RNA and proteins at the level of atomic structure. Dr. Ferré-D’Amaré is also interested in the role of RNA molecules in gene regulation and signal transduction (e.g., riboswitches, non-coding mRNA domains that directly bind to specific small molecules or macromolecules and control transcription, translation, or splicing). He and his colleagues focus on the way RNA molecules fold into three-dimensional structures and how they are modified post-transcriptionally, and use this information rationally to design new molecular tools. Finally, he uses the dual function of RNA molecules as information carriers and catalytic agents to artificially evolve them, study their properties, and engineer them.

Among his varied research interests, Dr. Ferré-D’Amaré has several programs with strong translational implications. The first is a discovery initiative for small molecule antibiotic leads that bind to riboswitches. Riboswitches have been largely ignored as targets for drug discovery, yet their central role is clear in clinically important phenomena such as bacterial biofilm formation. Biofilms are assemblages of bacteria that adhere to biological and non-biological substrates and resist existing treatment. Their formation is regulated by cyclic-di-GMP-sensing riboswitches. Dr. Ferré-D’Amaré's laboratory has identified many compounds that bind specifically to bacterial riboswitches. He is currently developing these leads into more potent molecules, in collaboration with colleagues at Cambridge University, NCATS and NCI. Unlike mammalian cells, bacteria and yeast have rigid cell walls that form a protective exoskeleton. Dr. Ferré-D’Amaré’s second translational research focus is on the role of a catalytic RNA—glmS—in controlling the synthesis of the bacterial cell wall. GlmS operates not only as a catalytic RNA but also as a riboswitch and controls cell wall biosynthesis. By determining its crystal structures in multiple functional states, Dr. Ferré-D’Amaré's laboratory has generated "molecular movies" of the glmS ribozyme in action. These studies have revealed how the glmS ribozyme can employ a small molecule as a coenzyme. The glmS ribozyme is being studied as a potentially valuable target for novel antibiotics, and also an experimental platform with which to understand how RNA targets can evolve antibiotic resistance. Finally, Dr. Ferré-D’Amaré's interest in non-coding RNA biology has led him to structural and molecular engineering studies of fluorescent RNAs. Much like green fluorescent protein (GFP) and its variants transformed the study of proteins, fluorescent RNAs have the potential to revolutionize the in vivo study of the tens of thousands of non-coding RNAs that have been discovered in the human transcriptome. Dr. Ferré-D’Amaré and colleagues elucidated the structural basis for fluorescence of several RNA-chromophore complexes, and are leveraging this knowledge to generate optimized tools to study the synthesis, maturation, targeting, localization and turnover of RNAs that play essential roles in metabolism, development and disease progression.
  Methods

            Methods

New methods drive progress in the experimental sciences. In addition to the development of techniques for the synthesis and characterization of biological molecules, we have a long-standing interest in methods to enable the preparation of highly-ordered crystals of nucleic acids, proteins, and their complexes. These are key to their structure determination by X-ray crystallography. Important advances include domain elucidation by mass spectrometry, construct engineering to improve crystallizability, and pre-crystallization analysis of monodispersity. Another area of biomedical research where we have contributed new methods is in the analysis of in vitro selection experiments.• Lau, M.W. & Ferré-D'Amaré, A.R.
