Latest Patents

One of Erwin's latest patents focuses on the production of lysosomal enzymes in plants through transient expression. This invention involves constructing and expressing recombinant expression constructs that comprise coding sequences of human or animal lysosomal enzymes within a plant expression system. The system allows for post-translational modification and processing, resulting in a recombinant gene product that exhibits enzymatic activity. The invention has been demonstrated through examples where transgenic tobacco plants express human glucocerebrosidase and human α-galactosidase nucleotide sequences. The recombinant lysosomal enzymes produced can be utilized for various purposes, including enzyme replacement therapy for lysosomal storage diseases.

Another significant patent by Erwin details a method for compiling a functional gene profile in a plant by transfecting a nucleic acid sequence from a donor plant into a different host plant in an anti-sense orientation. This method allows for the determination of changes in phenotype or biochemistry of the host plant. A viral vector functional genomic screen has been developed to identify nucleotide sequences in transfected plants by knocking out endogenous gene expression. The invention exemplifies how genes encoding GTP binding proteins in one plant can silence endogenous gene expression in another.
