Localization of phosphorylated alphaB-crystallin to heart mitochondria during ischemia-reperfusion.

The cytosolic small heat shock protein alphaB-crystallin (alphaBC) is a molecular chaperone expressed in large quantities in the heart, where it protects from stresses such as ischemia-reperfusion (I/R). Upon I/R, p38 MAP kinase activation leads to …

The characterization of the ascorbic acid-mediated alpha-amidation of alpha-melanotropin in cultured intermediate pituitary lobe cells.

Previous studies have shown that cultured rat intermediate pituitary lobe cells lose the ability to form ACTH-(1-13)NH2-related molecules (alpha MSH) and instead produce ACTH-(1-14)-related peptides. In vitro studies have shown that peptidylglycine …

Acetylation of alpha-melanotropin and beta-endorphin in the rat intermediate pituitary. Subcellular localization.

The subcellular site of the further processing (NH2-terminal acetylation and COOH-terminal proteolysis) of beta-endorphin-sized molecules in the rat intermediate pituitary has been studied. Rat intermediate pituitary primary cultures that had been …

Characterization of the peptide acetyltransferase activity in bovine and rat intermediate pituitaries responsible for the acetylation of beta-endorphin and alpha-melanotropin.

Subcellular fractionation studies on the post-translational processing of pro-adrenocorticotropic hormone/endorphin in rat intermediate pituitary.

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 …
