Abstract
The present invention relates to a method for detecting a substance having an activity to inhibit HIV infection rapidly, economically and safely. The present invention uses the characteristics that if a function of transmembrane protein gp41 of HIV is inhibited, HIV infection is also inhibited, and therefore the function of gp41 depends on the interaction between two helical structures of gp41. The method of the present invention is to detect a substance to inhibit HIV infection by an immunoassay using the interaction between the variant protein Trx-N, which is prepared by binding the N-terminal helical domain of gp41 to Trx (thioredoxin) and the variant protein GST-C, which is prepared by binding the C-terminal helical domain of gp41 with GST-C (Glutathione S-transferase). This immunoassay can be used for automatic detection of the substance to inhibit the activity of gp41 can be carried out by the method. As a result, it is possible to investigate HIV infection-inhibiting activity of a number of previously known compounds or natural compounds, and it can attribute to the development of therapeutic agent of HIV infection.
