Abstract

REICH, G., K. E. DOBLE AND M. J. GREENBERG. Protein phosphorylation in snail cardiocytes stimulated with molluscan peptide SCPb. PEPTIDES 18(9) 1311-1314, 1997.-Dissociated muscle cells prepared from hearts ofthe pulmonate snail Helix aspersa were used to study signal transduction induced by molluscan cardioactive peptides. The effects of SCPb onthe cAMP levels of whole hearts and the cell preparation were compared. The cells responded to SCPb with a dose-dependent increase in cAMP that had the same structure-activity relations as seen in the intact tissue. SCPb increased the phosphorylation of a 53 kDa protein in a dose dependent manner; threshold was 10(-9) M. The SCPb-induced phosphorylation was mimicked by forskolin and 8-CPT-cAMP. FMRFamide stimulationhad no effect on the phosphorylation of this protein. (C) 1997 Elsevier Science Inc.
