Abstract

Proteins with inhibin activity having a weight of about 32,000 daltons. The molecule is composed of two chains having molecular weights of about 18,000 and about 14,000 daltons, respectively, which are bound together by disulfide bonding. The 18K chain is obtained from the human inhibin gene and has the formula: H-Ser-Thr-Pro-Leu-Met-Ser-Trp-Pro-Trp-Ser-Pro-Ser-Ala-Leu-Arg-Leu-Leu-Gln- Arg-Pro-Pro-Glu-Glu-Pro-Ala-Ala-His-Ala-Asn-Cys-His-Arg-Val-Ala-Leu-Asn-Ile -Ser-Phe-Gln-Glu-Leu-Gly-Trp-Glu-Arg-Trp-Ile-Val-Tyr-Pro-Pro-Ser-Phe-R.sub. 65 -Phe-His-Tyr-Cys-His-Gly-Gly-Cys-Gly-Leu-His-Ile-Pro-Pro-Asn-Leu-Ser-Leu-P ro-Val-Pro-Gly-Ala-Pro-Pro-Thr-Pro-Ala-Gln-Pro-Tyr-Ser-Leu-Leu-Pro-Gly-Ala- Gln-Pro-Cys-Cys-Ala-Ala-Leu-Pro-Gly-Thr-Met-Arg-Pro-Leu-His-Val-Arg-Thr-Thr -Ser-Asp-Gly-Gly-Tyr-Ser-P e-Lys-Tyr-Glu-Thr-Val-Pro-Asn-Leu-Leu-Thr-Gln-His-Cys-Ala-Cys-Ile-OH, wherein R.sub.65 is Ile or Arg. The 18K chain is connected by disulfide bonding to the 14K chain.
