FIELD: medicine.
SUBSTANCE: there is offered a method for identification of an inhibiting candidate substance which enables inhibits hepsin-activated HGF. The method is based on comparing the degree of activation of pro-HGF substratum in a sample containing hepsin, pro-HGF and the analysed candidate substance, with the degree of activation of pro-HGF substratum in the reference sample who not containing the candidate substance. Also there is offered an agent for inhibiting hepsin and hepatocyte growth factor reaction containing a sequence of Kunitz domain which represents a KD-1 sequence of Kunitz domain HAI-1 or HAI-1B, or one or both Kunitz domains HAI-2.
EFFECT: invention allows identifying physiological hepsin modulators.
