Home: Overview


The synthesis of proteins using genetic information is a fundamental process in all life forms. In higher organisms, the process is tightly controlled and much of this regulation occurs during the initial steps of translation. Translational control plays an important role in many key life processes, including early embryonic development, learning and memory, and the response to cellular stress. Although translation initiation is a fundamental and indispensable process, many of its aspects are poorly understood. We employ biochemical, mutational, and structural biology approaches to understand the molecular details of the initial steps of protein synthesis and to figure out how it is regulated. Understanding translation initiation and its regulation will be beneficial for many human disorders and cancers. In addition, it may provide avenues for the development of strategies for modulation of translation initiation and development of novel therapeutic strategies against bacterial, fungal, and viral infection.
