here , we have used the n-terminal amino-acid sequence data on the subunits of each inhibin to identify cloned complementary dnas encoding the biosynthetic precursors and report that inhibins are the product of a gene family that also includes transforming growth factor-beta ( tgf-beta ) and whose structural organization is similar to that of pituitary and placental glycoprotein hormones .
