Dynamin mediated diseases and associated methods and products
This invention relates generally to the treatment of cathepsin or dynamin mediated diseases, such as proteinuria, cancer, and cognitive disease and related products. Diagnostic and other assays are also provided, as well as methods for podocyte cell gene transfer.
1. An isolated polypeptide comprising the amino acid sequence of SEQ ID NO: 1, wherein the isolated polypeptide contains at least one mutation rendering it resistant to proteolytic-cleavage but does not impair its ability to form actin stress fibers in podocytes, wherein said at least one mutation is L356Q or G358V.
2. An isolated polypeptide comprising the amino acid sequence of SEQ ID NO: 1, wherein the isolated polypeptide contains the mutation R725A.
3. The isolated polypeptide of claim 1 , wherein the mutations are: L356Q and G358V.
4. A pharmaceutical preparation comprising the isolated polypeptide of claim 1 , and a pharmaceutically acceptable carrier.
5. A pharmaceutical preparation comprising the isolated polypeptide of claim 2 , and a pharmaceutically acceptable carrier.
