Annotations for the interactionfigure legend:f5C
comment:"\"However, upon immunoprecipitation of sMT1-MMP from tissue extracts and fluids with polyclonal antibodies against the hinge region of MT1-MMP and western blot analysis, using monoclonal antibodies against human TIMP-2, an immunoreactive band of ~ 21 kDa, migrating as the human recombinant TIMP-2, was observed in all samples (Fig. 5A). Since polyclonal antibodies against the hinge region of MT1-MMP used for immunoprecipitation, do not recognize TIMP-2 (Fig. 5B), and they did not show non specific reaction with monoclonal antibodies against TIMP-2 (Fig. 5A), these results suggest that TIMP-2 co-precipitated with sMT1-MMP because it was already in complex with it. Consequently, it appears that the sMT1- MMP in tissue extracts and fluids exists in a latent form and yet, bound to TIMP-2. These results were further confirmed by reverse immunoprecipitation with monoclonal antibodies against TIMP-2 and western blotting using polyclonal antibodies against the hinge region of MT1-MMP. Only one immunoreactive band of ~ 57 kDa, corresponding to sMT1- MMP, was observed in all samples (Fig. 5C).\""
