Research interests

Dr. Darżynkiewicz's research concentrates on organic chemistry and biochemistry of nucleic acids. Since middle 80. he has been involved in studying the role of 5' mRNA and 5' U snRNA cap structures in gene expresssion regulation: initiation of protein translation, pre-mRNA splicing and RNA intracellular transport. He has designed and synthesized many model cap analogues which appeared to be invaluable tools for research into molecular mechanisms of the above processes. For example, the synthetic trimethyl guanosine cap anlogues enabled to establish the signalling role of trimethylguanosine cap structure in nuclear import of some of U snRNAs. Both, synthetic cap analogues and affinity resins based on them, helped to isolate and characterize several new regulatory factors, like nuclear cap binding complex (CBC) which is engaged in pre-mRNA splicing, or new cytoplasmic eIF4E isoforms from nematode C.elegans whose functions are under investigation. Selected cap analogs have been used in comprehensive biophysical studies of the molecular recognition of cap structures by specific protein factors. These type of studies are being performed by physicists from Department of Biophysics, who Dr. Darżynkiewicz closely collaborates with (R. Stolarski and J. Antosiewicz). He developed a broad collaboration with biochemical groups from many leading laboratories, like with Dr. R.Rhoads (Louisiana State University in Shreveport, USA), Dr. N.Sonenberg (McGill University in Montreal), Dr. S.Burley (Rockefeller University in New York), Dr. I.Mattaj (EMBL, Heidelberg), Dr. S.Cusack (EMBL, Grenoble).

Since 1990 Dr. Darżynkiewicz's research has been continuously supported by the grants from The Polish Committee for Scientific Research. During 1998-2001 he was a coinvestigator in the Polish-US-Canadian international HFSP grant.

Dr. Darżynkiewicz has authored over 90 original publications and reviews. His publications have been cited over 1000 times in the scientific literature.
