NK (natural killer) cells, with their ability to identify antigens and extraneous substances, available in the organism through various moleculary receptors, are an important component of the immune system. The NKR-P1A and NKR-P1B proteins belong to the lectin receptors of natural killer cells. Primary ligands of lectin receptors comprise terminal oligosaccharides of glycoproteins on the surface of target (e.g. tumor) cells. The interaction between carbohydrate structures on the surface of antigens and their binding partners on NK receptors is followed by triggering the effector function of NK cells against the targets. The NK cells and NK receptors findings and their interactions with ligands are greatly utilized in the treatment of cancer, viral and autoimmune diseases. Heterologous protein production in the eukaryotic organism brings a lot of advantages. Unlike the prokaryotic organism, the methylotrophic yeast Pichia pastoris has the capability of performing many posttranslational modifications resulting in production of biological active protein molecule. Usually, the P. pastoris expression system disposes of high level protein expression and is also generally regarded as being faster, easier, and less expensive to use than expression systems derived from other eukaryotes. In this thesis, I...
