Nucleic acid encoding .beta. chain prodomains of inhibin and method for synthesizing polypeptides using such nucleic acid
First Claim
1. A method for producing an inhibin beta b chain prodomain polypeptide, said prodomain comprising the sequence Cys Thr Ser Cys Gly Gly Phe Arg Arg Pro Glu Glu Leu Gly Arg Val Asp Gly Asp Phe Leu Glu Ala Val or the sequence Arg Ala Ala Gly Ala Glu Glu Glu Leu Gly Arg Leu Asp Gly Asp Phe Leu Glu Ala Val, said method comprising (a) constructing a vector that comprises a nucleic acid encoding said prodomain, (b) transforming a host cell with said vector, and (c) culturing the transformed cell under conditions appropriate for expression of said polypeptide.

Abstract
DNA encoding the prepro inhibin α and β chains has been isolated. This DNA is ligated into expression vectors and used to transform host cells for the preparation of inhibin or activin. Also provided are prohormone domains and other inhibin α and β chain derivatives having therapeutic or diagnostic interest. The compositions provided herein are useful in the manipulation of fertility in animals.
