Publication Abstract from PubMed

Hepsin is a type II transmembrane serine protease that is expressed in several human tissues. Overexpression of hepsin has been found to correlate with tumor progression and metastasis, which is so far best studied for prostate cancer, where more than 90% of such tumors show this characteristic. To enable improved future patient treatment, we developed a monoclonal humanized antibody that selectively inhibits human hepsin and does not inhibit other related proteases. We found that our antibody hH35 potently inhibits hepsin enzymatic activity at nanomolar concentrations. Kinetic characterization revealed non-linear, slow, tight-binding inhibition. This correlates with the crystal structure we obtained for the human hepsin-hH35 antibody Fab fragment complex, which showed that the antibody binds hepsin around a3-helix, located far from the active center. The unique allosteric mode of inhibition of hH35 is distinct from the recently described HGFA (Hepatocyte Growth Factor Activator) allosteric antibody inhibition. We further explain how a small change in the antibody design induces dramatic structural rearrangements in the hepsin antigen upon binding leading to complete enzyme inactivation.
