Acp29AB is absent from the reproductive tracts of virgin females and females 5 min ASM (after the start of mating), but is transferred to the female reproductive tract by 7 min ASM. Acp29AB localizes to the spermathecum 1 hour after mating and is also detectable in the hemolymph of the mated female.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

If females remate frequently relative to the duration of sperm storage and rate of sperm use, sperm displacement may be an important component of male reproductive success. Significant association has been found between Acp29AB mutant male sperm and the ability to resist displacement by subsequent sperm. There is no correlation between the ability to displace resident sperm and the ability to resist being displaced by subsequent sperm, this lack of correlation suggests that different mechanisms mediate that the two components of sperm displacement.
May promote replacement of sperm already stored by a female.
