Decoding Genetic Information In Translation
The genetic code was established over two billion years ago and became universally adopted by all living organisms. The rules of the code--which relate specific nucleotide triplets to specific amino acids--are established by aminoacylation reactions catalyzed by aminoacyl tRNA synthetases. In these reactions, an amino acid is associated with a specific nucleotide triplet of the genetic code, by virtue of being linked to a specific tRNA that harbors the anticodon triplet cognate to the amino acid. Because of their central role in establishing the rules of the code, the tRNAs are thought to have arisen quite early, perhaps in the context of an RNA world. The synthetases may have been amongst the earliest proteins to appear, perhaps replacing ribozymes that catalyzed the aminoacylation of primordial tRNAs. The Schimmel laboratory is interested in understanding all aspects of these systems.
Our present work focuses on the discovery of the large new biology that flows out of the tRNA synthetases. These enzymes are now known to be secreted, to have nuclear functions, and to pervade most or all parts of human biology with activities that are distinct from their catalytic function of charging tRNA. The laboratory uses methods and logic of molecular and cell biology, chemistry, and structural analysis to more deeply investigate these novel functions that have a fundamental role in maintaining organismal homeostasis, and in developing and regulating nervous, vascular, and immunological systems. The research is leading to the development of a broad new class of therapeutics to treat and cure human diseases.
