Abstract

The ribosomal protein S6 in exocrine cells is phosphorylated during stimulated during stimulation of exocytosis by cAMP‐dependent or calcium‐dependent agonists. Under both conditions the same tryptic S6 phosphopeptides (termed A, B, and C) were found [Padel, Kruppa, Jahn & Söling (1983) FEBS Lett. 159, 112–118]. Studies have now been made of the phosphorylation pattern of protein S6 from purified guinea pig parotid ribosomes following in vitro phosphorylation with calmodulin‐dependent, phospholipid‐dependent, and cAMP‐dependent protein kinases. Only the phospholipid‐dependent enzyme led to the phosphorylation of peptides A, B, and C, while the cAMP‐dependent enzyme phosphorylated only peptides A and C, and the calmodulin‐dependent enzyme did not phosphorylate any of the phosphopeptides found in S6 from unstimulated or stimulated intact cells. Guinea pig parotid microsomes contain substantial phospholipid‐dependent protein kinase activity. Stimulation of intact parotid glands with tetradecanolyphorbol acetate led to a significant phosphorylation of S6 and a similar tryptic S6 phosphopeptide pattern as seen with carbamoylcholine. It is concluded that activation of phospholipid‐dependent protein kinase is responsible for the phosphorylation of protein S6 during stimulation with calcium‐dependent and cAMP‐dependent secretagogues.
