The model of ICAM-1 and LFA-1 molecular interaction was used to test the application of the
Molecular Recognition Theory for the identification of several discontinuous binding regions,
i.e. ligand-receptor sites, within large antigenic molecules. Molecular Recognition Theory is an
applicable heuristic algorithm for identification of possibly interacting amino acid pairs in short
linear epitope/paratope sites within larger molecules. However, in order to achieve better efficiency
this heuristic algorithm of molecular recognition has to be combined to several other
procedures: molecular hydropathy analyses, secondary structure prediction methods and protein
database search. The limitation of the combined MRT-hydropathy analyses is in the fact
that it cannot explain 3D protein interactions, but it can be a valuable starting point for a more
complex computational and experimental analysis.
