CHIMERIC RELAXIN POLYPEPTIDES COMPRISING AN A AND B CHAIN DERIVED FROM DIFFERENT RELAXIN FAMILY PEPTIDES

摘要

Modified relaxin polypeptides are disclosed wherein the B chain comprises the core sequence CGRxxxRxxI/VxxCG (SEQ ID NO: 1), specifically KLCGRELVRAQIAIC. Chimeric polypeptides comprising a B chain with the core sequence CGRxxxRxxFVxxCG (SEQ ID NO: 1) and an A chain from a heterologous relaxin family peptide are also disclosed. Specifically, chimeric polypeptides comprising a B chain from relaxin-2, and an A chain from relaxin- 1, relaxin-3, insulin, IGF-I, IGF-II, INSL3, INSL4, INSL5 or INSL6, are disclosed.
