Abstract: The present invention provides a purified and isolated nucleic acid molecule encoding serine protease (Met-ase) having Met-ase activity but not Asp-ase activity and a molecular weight of about 30,000 daltons on SDS PAGE under reducing and non-reducing conditions. The present invention also provides a vector comprising this nucleic acid molecule, a prokaryotic or eukaryotic host cell stably transformed or transfected with the vector, as well as a method for detecting this nucleic acid in a sample.

Abstract: The present invention provides a method of treating a neurodegenerative pathology in a human patient. This method includes selecting a patient for monitoring for the presence of a neurodegenerative pathology associated with enhanced Calpain activity and monitoring the patient for indicia of the onset or existence of such a pathology. In response to the detection of any such indicium of the presence or onset of the pathology, a therapeutically efficacious amount of a Peptide Ketoamide compound, or a pharmaceutically acceptable salt or derivative thereof, together with a pharmaceutically acceptable carrier is administered. The invention also provides additional methods of treatment and pharmaceutical compositions using Peptide Ketoamides, Peptide Ketoacids and Peptide Ketoesters.
