The present invention relates to a method for analyzing the interaction
between HIF-1 peptide and VBC protein using fluorescence polarization,
more precisely, a method for quantitative analysis of formation of
HIF-1-VBC protein complex which is composed of the steps of 1) preparing
a fluorescent probe by attaching a fluorescein to hydroxyproline
containing HIF-1 peptide; 2) reacting the fluorescent probe with VBC
protein; and 3) measuring the fluorescence polarization of the above
reactant and then comparing the fluorescence polarization with that of
the fluorescent probe itself to investigate the changes of fluorescence
polarization; a method for screening an inhibitor of the binding of HIF-1
peptide and VBC protein using the above method; and a method for
analyzing the activity of prolyl hydroxylase using the above method. The
method of the present invention enables simple analysis of the
interaction between HIF-1 peptide and VBC protein by observing changes of
fluorescence polarization and thus, it can be effectively used for
high-speed screening using a well plate.
