Male accessory gland proteins (Acps) in Drosophila are components of the seminal fluid and are transferred to females during copulation. In mated females, Acps enhance egg production, augment sperm storage, induce refractory mating behaviors. and affect the female's longevity. To address the functions of eight previously uncharacterized Acps and further analyze five others, we determined the tissues to which they target after transfer to females. Each Acp has multiple targets and is unique in its pattern of localization. Within the reproductive tract, Acps target to the uterus, oviduct, sperm storage organs, ovary and oocytes. Some Acps also leave the reproductive tract. to enter the hemolymph. Some Acps are detected oil the surface of eggs laid by mated females but were not detectable within those eggs. Our results call help to identify the likely functions of these Acps as well as to create models for the mechanism of action of Acps., (C) 2005 Elsevier Ltd. All rights reserved.
