Rat intermediate pituitary cells in primary culture display a time-dependent loss of the ability to produce COOH-terminally alpha-amidated alpha MSH (Glembotski, C.C., Eipper, B.A., and Mains, R.E. (1983) J. Biol. Chem. 258, 7299-7304). Instead of …
An enzymatic activity capable of producing an alpha-amidated peptide product from its glycine-extended precursor has been identified in secretory granules of rat anterior, intermediate, and neural pituitary and bovine intermediate pituitary. High …
The structures of the altered alpha-melanotropin (alpha MSH or alpha-N-acetyl-ACTH(1-13)NH2)-related molecules produced by cultured rat intermediate pituitary cells were investigated. Peptide analyses demonstrated that the alpha MSH-related molecules …
The production of alpha-melanotropin (alpha-N-acetyl-ACTH(1-13)NH2 (alpha MSH) in rat intermediate pituitary was investigated using reverse phase high performance liquid chromatography, immunoassays, and biosynthetic labeling. Extracts of rat …
The subcellular localization of the post-translational processing steps which occur in the conversion of pro-adrenocorticotropic hormone (ACTH)/endorphin into beta-endorphin-sized molecules in rat intermediate pituitary has been studied. Primary cell …
