Mammalian spermatozoa acquire the ability to fertilize ovocyte during their transit throught epididymis where they are submitted to biochemical modifications under environmental control. These modifications mainly concern sperm surface proteins which are minor coumpounds. In boar, we developped a methodology based on labeling, differencial extraction and purification of sperm surface proteins which allowed identification by nano-LC/MS/MS of more than 170 compounds. By the help of quantitative approaches (1D-2D electrophoresis, iTRAQ) comparative analysis of these proteins in successive epididymal regions ensured identification of biomarkers of maturation. Sperm surface proteins were caracterized in two other species: bull and horse. Thanks ...
