Cyclic nucleotide phosphodiesterases in larval brain of wild type and dunce mutant strains of Drosophila melanogaster: isoenzyme pattern and activation by Ca2+/calmodulin

M Solti et al. Biochem Biophys Res Commun. .

Abstract

Like adult heads and whole flies, larval brains of wild type Drosophila melanogaster contain two major soluble cyclic nucleotide phosphodiesterases, forms I and II. Larval brains of the learning-defective mutant strain, dunceM11, contain only the form I enzyme. In both wild type and dunce strains the form I enzyme is activated by Ca2+/calmodulin. A time-dependent loss of this Ca2+ activation was observed.
