A peptide with high potency and intrinsic activity for stimulating the secretion of corticotropin-
like and β-endorphin-like immunoactivities by cultured anterior pituitary cells has been
purified from ovine hypothalamic extracts. The primary structure of this 41-residue
corticotropin-and β-endorphin-releasing factor has been determined to be: H-Ser-Gln-Glu-
Pro-Pro-Ile-Ser-Leu-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-Glu-Met-Thr-Lys-Ala-
Asp-Gln-Leu-Ala-Gln-Gln-Ala-His-Ser-Asn-Arg-Lys-Leu-Leu-Asp-Ile-Ala-NH2. The synthetic …
