ProteomicsGenotype-by-environment interactions influence the composition of the Drosophila seminal proteome
Ejaculate proteins are key mediators of post-mating sexual selection and sexual conflict, as they can influence both male fertilization success and female reproductive physiology. However, the extent and sources of genetic variation and condition dependence of the ejaculate proteome are largely unkn...

ProteomicsIdentification of novel ejaculated seminal fluid proteins in a seed beetle and division of labour across male accessory reproductive glands
The male ejaculate contains a multitude of seminal fluid proteins (SFPs), many of which are key reproductive molecules. However, the identification of SFPs is notoriously difficult and a detailed understanding of this complex phenotype has only been achieved in a few model species. We employed a rec...

ProteomicsSocial status and ejaculate investment in the house mouse c4pr_liv
Sperm competition theory predicts that males should tailor ejaculates according to their social status. Here we test this in a model vertebrate, the house mouse (Mus musculus domesticus), combining experimental data with a quantitative proteomics analysis of seminal fluid composition. Our analyses r...

ProteomicsBMP-inhibition in Drosophila secondary cells remodels the seminal proteome, and self and rival ejaculate functions
Seminal fluid proteins (SFPs) exert potent effects on male and female fitness. These rapidly evolving and molecularly diverse proteins derive from multiple male secretory cells and tissues. In Drosophila melanogaster most SFPs are produced in the accessory glands, which are composed of ~1000 fertili...

ProteomicsProteomic differences between Drosophila melanogaster female reproductive tract tissue and fluid and their postmating responses
Fertility depends on the progression of complex and coordinated postmating processes within the extracellular luminal environment of the female reproductive tract (FRT). To achieve a more comprehensive level of knowledge regarding female-derived proteins available to interact with the ejaculate, we ...

ProteomicsThe proteome of pig spermatozoa is remodelled during ejaculation
Proteins are essential for sperm function, including fertilizing capacity. Pig spermatozoa, emitted in well-defined ejaculate fractions, clearly vary in their functionality, which would be related to differences in protein composition. This study aimed firstly to update the porcine sperm proteome an...
