dc.description.abstract | Insulin and insulin-like growth factor 1 (IGF-1) are peptide hormones that are important regulators of cellular metabolism, proliferation and apoptosis. Disruptions in signalling pathways may cause a whole range of diseases from diabetes mellitus type 1 and type 2 to cancer or neurodegenerative diseases. The cellular response to these hormones is mediated by insulin (IR) and IGF-1 receptors (IGF-1R) with a tyrosin-kinase activity. Receptors are created as hetero-tetramers of two extracellular α-subunits and two intracellular β-subunits. Studies of receptor structures try to elucidate the basic principles of the interaction of receptors with their ligands. However, the role of some amino-acid residues in binding remains unclear. It was suggested that the arginine 704 of IGF-1R may interact with Glu58 IGF-1. In comparison with IGF-1R, the equivalent arginine 717 IR was not associated with an important role in insulin binding in previous studies. This thesis is focused on clarifying the role of Arg704 IGF-1R and for comparison analogically on Arg717 IR isoform A (IR-A) in ligand binding to the receptors. Therefore, mutant variants of IGF-1R in positions His697 and Arg704 and variants IR-A in positions His710 and Arg717 were created. The role of histidines 697 IGF-1R and 710 IR was already elucidated... | en_US |
