Molecular analysis of the serine/threonine kinase Akt and its expression in the mosquito Aedes aegypti.
A key component of the insulin-signalling pathway, the protein kinase Akt, was identified and cloned as a cDNA from ovaries of the mosquito Aedes aegypti. An ortholog gene was found in the Anopheles gambiae genome database, and like other Akts, both mosquito Akts possess pleckstrin homology domains for membrane binding and a serine/threonine kinase domain. When Ae. aegypti ovaries were treated with bovine insulin in vitro, a putative Akt was threonine-phosphorylated, as expected for Akts. AaegAKT was only expressed in embryos for the first 6 h after oviposition and in ovaries before and during a gonotrophic cycle.
