Dubin Lab | Protein Crystallography

X-ray crystallography allows to determine structures of biological macromolecules with atomic resolution, providing unparalleled insight into structure-function relationships.




Scope of research

The Protein Crystallography Research Group lead by Grzegorz Dubin focuses on determination, interpretation and understanding of X-ray structures of biological molecules involved in:

  • cancer,
  • diabetes
  • transmembrane protein transport.

We also provide expertise in collaborative undertakings in multiple areas of basic and applied research.

We are primarily interesting study in interactions of proteins and proteins and low molecular weight substances within the subject of carcinogenesis and bacterial pathogenesis. Currently were realize our own projects involving structural characterization of kinases of essential role cancer, p53 pathway, bacterial proteases of unknown catalytic mechanism and staphylococcal proteases. In parallel to the crystallographic studies we also develop aptamer selection techniques (especially single-stranded DNA) against targets of importance in cancer. In addition to our own research, we are also involved in broad scientific collaboration and cooperation with the industry on other subjects whenever problem scan be solved by X-ray crystallography of proteins. We invite anyone interested in collaboration.

Research methodology and specialized equipment

The X-ray Crystallography Laboratory of MCB has extensive experience in solving protein structures and the structures of complexes. The primary laboratory equipment consists of an X-ray diffractometer (RigakuMicroMax-007 HF) with CCD and IP detectors. Crystallization screening is carried out using an automatic pipetting station (Phoenix RE). Laboratory is also exceptionally well equipped for expression, purification and analysis of proteins.
