Biochemical Signaling

Scientists in the Biochemical Signaling area probe the molecular mechanisms accounting for changes in cell metabolism that mediate the physiological adaptation of living cells in response to alterations in their environment.

These cellular responses often involve sequential biochemical reactions that form signaling cascades to coordinately regulate multiple cell functions. Some of the biochemical mechanisms studied in these signaling cascades include post-translational modifications of proteins such as phosphorylation, methylation, lipidation, and ubiquitination. Other mechanisms involve allosteric regulation of molecular function, including protein-protein and protein-DNA interactions.

The goal of these studies is to:

  • Understand the principles of coordinated molecular regulation at a biochemical level and
  • Demonstrate the importance of these biochemical regulatory mechanisms in a cellular context
