Molecular evolution of the crustacean hyperglycemic hormone family in ecdysozoans.

ABSTRACT:

Background

Crustacean Hyperglycemic Hormone (CHH) family peptides are neurohormones known to regulate several important functions in decapod crustaceans such as ionic and energetic metabolism, molting and reproduction. The structural conservation of these peptides, together with the variety of functions they display, led us to investigate their evolutionary history. CHH family peptides exist in insects (Ion Transport Peptides) and may be present in all ecdysozoans as well. In order to extend the evolutionary study to the entire family, CHH family peptides were thus searched in taxa outside decapods, where they have been, to date, poorly investigated.

Results

CHH family peptides were characterized by molecular cloning in a branchiopod crustacean, Daphnia magna, and in a colle
