The basic concept in which our research relies on is that understanding of disease mechanisms is through protein interactions. The ongoing genomes wide functional proteome mapping effort requires sufficient tools and a number of approaches. Our aim is to resolve chemistries and biochemistries of macromolecular interactions, thus the approach is reductionist. By limiting research to one or a related set of interactions of possibly known biological function we further highlight an interaction in terms of its strength, rate and duration, and via identification of interaction sites. The protein interaction interphases (epitopes versus paratopes) as areas stand for a fraction of an average protein surface area. Thus, recognition of a few amino acid residue side chain, be it by protein, nucleic acid, sugar or lipid interaction, may in relevant biological setting have a biochemical and a biological consequence.

 Peptide and protein chemistries offer excellent views to chemistries and biochemistries of protein interaction interphases and thus to functions of proteome. In peptide chemistry, functional centres of proteins are targeted directly, in combinatorial peptide chemistry through binding sites (arrays, libraries, chips, sensors), and in bioactive molecules via capture of independent functions (peptides and their mimets that are increasingly important in biopharma).

Cell culture model and tissue imaging, blood circulation and body secreta diagnostics, all benefit greatly from light sensitive detection, in these, peptide chemistry solutions allow macromolecular targeting and thereby assist mapping of the functional proteome.  

In our own research we use Puumala hantavirus as the model in mapping of functional interaction sites in a virus proteome. We aim through this research to indentification of antiviral targets and drug discovery. A viral genome consist of a few up to a hundred genes which, compared to the human genome (~30.000 genes) is small. Still, a virus infection, from its reproduction in cells to clearance from infectious site, leads to many host interactions (tens or hundreds). These interactions cause alterations, repressions and activations in host protein functions and gene expressions, and as a consequence an infectious disease.

We have through collaborative research at Haartman Institute provided background information especially for proteins that are important in infection, cancer and cell biologies (see References).

Peptide and Protein Laboratory at Haartman Institute is dedicated to synthetic peptide chemistry and protein interaction studies. With communally recruited instrumentation we collaborate in basic research and support research and development in medical diagnostics and in drug discovery. Our research contributions in macromolecular interaction kinetics and peptide chemistry may have impacts in so called translational research from basic research to applications in practical medicine and pharmacology.
