Role of Ca2+/calmodulin-dependent protein kinase II in Drosophila photoreceptors.

Abstract excerpt

Ca(2+) modulates the visual response in both vertebrates and invertebrates. In Drosophila photoreceptors, an increase of cytoplasmic Ca(2+) mimics light adaptation. Little is known regarding the mechanism, however. We explored the role of the sole Drosophila Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) to mediate light adaptation. CaMKII has been implicated in the phosphorylation of arrestin 2 (Arr2)....
