    Abstract

    In the present study, we examined the effects of reagents that elevate cAMP concentration on protein phosphorylation in Drosophila brain cells. Application of forskolin or dopamine to brain cells that were prelabeled with 32Pi enhanced phosphorylation of a 25-kDa protein (p25a). To identify p25a, we isolated the protein, and partial amino acid sequences were analyzed. Database searches showed that p25a is a J-domain protein, dJDP that contains the J-domain found in the DnaJ (heat shock protein 40) family of molecular chaperones. (C) 2000 Elsevier Science B.V.
