Adenylate cyclase in the Drosophila memory mutant rutabaga displays an altered Ca2+ sensitivity.

Adenylate cyclase in washed, crude membrane fractions prepared from the Drosophila conditioning mutant, rutabaga, displays an altered responsiveness to Ca2+. The results are of interest since the modulation of adenylate cyclase activity by Ca2+ has recently been suggested to play a role in molecular events that underlie memory formation.
