Abstract

See full text

Cancer, obesity, and diabetes are examples of PTP1B-related diseases. The invention herein provides embodiments of therapeutic methods and compositions for treating PTP1B related diseases by engineering peptides that bind to the functional spine of PTP1B to alter the conformation of the protein and inhibit a function of PTP1B. Molecules bind to amino acid residues of the functional spine of PTP1B, regulate the catalytic cycle, and treat PTP1B-related diseases. For example, molecules bind to at least one of Tyr152, Tyr153, His175, Thr178, Pro185, Phe191, Leu192, Asn193, Cys215, Gly218, Phe280, Val287, Trp291, Lys292, Leu294, Ser295, and Glu297 to reduce at least one symptom of a PTP1B related disease.
