Abstract: The invention is directed toward a human glycoprotein hormone having at least one, two, three, four, or five basic amino acids in the ?-subunit at positions selected from the group consisting of positions 11, 13, 14, 16, 17, and 20. The invention is also directed to a human glycoprotein where at least one of the amino acids at position 58, 63, and 69 of the ?-subunit of the human thyroid stimulating hormone are basic amino acids. The invention is further directed to a modified human glycoprotein hormone having increased activity over a wild-type human glycoprotein hormone, where the modified human glycoprotein comprises a basic amino acid substituted at a position corresponding to the same amino acid position in a non-human glycoprotein hormone having an increased activity over the wild-type human glycoprotein hormone.
