Laboratory of Structural Biology of Signaling Proteins

Laboratory of Structural Biology of Signaling Proteins

Our Laboratory is focused on structural biology (the relationship between the structure and function of certain groups of proteins), particularly we focus on the proteins which participate in the signal transmission in the cell. Among methods we use are recombinant protein expression, biophysical characterization, study of intermolecular interactions, protein structure and interaction surfaces. All these methods enable us to better understand the details how the activity and function of protein-protein complexes is regulated. Our research is focused mainly on:

  • Structural biology of 14-3-3 proteins and their complexes
  • Mechanism of regulation of proteinkisases CaMKK1, CaMKK2 and ASK1
  • Study of inhibition of protease caspase-2 and ligase Nedd4-2 by 14-3-3 protein
  • Study of DNA-binding domain of transcription factor FOXO4
