  • Patent number: 7381556
    Abstract: Modified proteins are disclosed that maintain enzymatic and insecticidal activity while displaying reduced or eliminated allergenicity. Epitopes which bind to anti-patatin antibodies were identified, and removed via site directed mutagenesis. Tyrosines were observed to generally contribute to the allergenic properties of patatin proteins. Removal of glycosylation sites was observed to reduce or eliminate antibody binding. Permuteins are also disclosed which have a rearranged amino acid sequence while retaining enzymatic activity. Deallergenized proteins and permuteins can be used as insecticidal materials, as nutritional supplements, and as immunotherapeutic agents.
    Type: Grant

  • Patent number: 5969105
    Abstract: The present invention is drawn to human stem cell factor receptor agonist polypeptides, nucleic acid molecules encoding same, methods of producing the agonist polypeptides from the nucleic acid sequences and therapeutic compositions comprising the agonist polypeptides. The polypeptides of the instant invention are derived from the sequnce of SEQ ID NO:1, wherein 1-23 amino acids are optionally deleted from the C-terminus and the N-terminus is joined to the C-terminus, either directly or through a linker and C- and N-termini are created between an amino acid pair chosen from 23-24 through 110-111 of SEQ ID NO:1, generating said human stem cell factor receptor agonist polypeptide. The human stem cell factor receptor agonist polypeptide may additionally be immediately be preceded by a (methionine.sup.-1), (alanine.sup.-1) or (methionine.sup.-2, alanine.sup.-1).
