ABSTRACT
Single-chain insulin/IGF-1 hybrid-[Ins/IGF-1(C)], single-chain porcine insulin precursor-(PIP), and B10Asp PIP were prepared by protein engineering. Their growth-promoting activities in mouse breast cancer cell line GR2H6 are 10, 0.2, and 2 times that of insulin, respectively, and 29%, 0.6%, and 6% of that of IGF-1, indicating that the C domain and 9Glu of IGF-1 are important for its growth-promoting activity. Given these results and previous reports, we propose that the C domain, 9Glu, and 23Phe-26Asn beta bend are involved in the growth-promoting functional region of IGF-1.
