FIELD: medicine.
SUBSTANCE: there is offered method for identification and/or verification of inhibitors of receptor tyrosine kinases that involves application of a new test system which represents a yeast host cell containing an expression vector including a nucleic acid sequence that encodes fused protein essentially consisting of a complete cytoplasmic part of analysed receptor tyrosine kinase and the dimerisation domain and, if necessary, in addition including anchoring sequence for fused protein in a membrane wherein expression of fused protein conduces to termination of cell proliferation. The method provides production of specified host cells being in contact with a candidate compound and identification of inhibitors of tested tyrosine kinase activity as a result of cultivation on the assumption that inhibition of tyrosine kinase activity with a candidate compound causes restoration of proliferation process.
EFFECT: prospected application of the invention is related to development of selective therapeutic, including anticancer, agents.
