title: Demonstration of an epidermal growth factor-dependent 58 kDa phosphoprotein secreted by rat kidney fibroblasts.
abstract: Epidermal growth factor and 12-O-tetradecanoylphorbol-13-acetate increased the amount of 32Pi found as phosphoserine in a major, hitherto not described 58 kDa phosphoprotein (pp58) secreted by normal rat kidney fibroblasts. Platelet-derived growth factor, insulin, nerve growth factor and fibroblast growth factor did not affect pp58 while transforming growth factor beta decreased the accumulation of radioactivity into pp58. Cycloheximide, actinomycin D and ammonium chloride suppressed the labelling of pp58.
