Protein Structures

Protein Structures

http://www.biomed.cas.cz/d312/index.php?section=home

Our group 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 by 14-3-3 protein
  • Study of DNA-binding domain of transcription factor FOXO4
  • Interaction  of cytoplasmatic domains of TRP channels

Projects

PIP2 and PIP3 interact with N-terminus region of TRPM4 channel

Transient receptor potential (TRP) channels are a wide family of non-selective ion channels responsible for monovalent and divalent cation influx into the cells. Members of this family are involved in many sensory processes. We identified two positively charged residues as having a crucial impact on PIP2/PIP3 binding.  More
