Two protein kinases have been partially purified from rabbit reticulocytes and shown to be activated by limited proteolysis with trypsin [S. M. Tahara and J. A. Traugh (1981)J. Biol. Chem. 256, 11558–11564; P. T. Tuazon, W. C. Merrick, and J. A. Traugh (1980)J. Biol. Chem. 255, 10954–10958]. Reticulocyte lysate was examined for protease activities which might be involved in activation of the protein kinasesin vivo.Two neutral proteases, differentially activated by Fe2+and Ca2+, were identified and partially purified. The Ca2+‐stimulated protease specifically activated protease‐activated kinase II; no effect was observed on protease‐activated kinase I. The Fe2+‐stimulated protease was not active on either protein kinase. The protease‐activated kinases were examined using initiation factors (eIF) and 40‐S ribosomal subunits as substrate. Protease‐activated kinase I phosphorylated one subunit of eIF‐3 (Mr130000), eIF‐4B and 40‐S ribosomal protein S10. Protease‐activated kinase II modified the β subunit of eIF‐2 (Mr, 53000) and 40‐S ribosomal protein S6. The substrate specificities are unique when compared with other cAMP‐dependent and cAMP‐independent protein kinases from reticulocytes.
