Data in support of peptidomic analysis of spermatozoa during epididymal maturation.

ABSTRACT: The final differentiation of the male germ cell occurs in the epididymal duct where the spermatozoa develop the ability to be motile and fertilize an ovum. Understanding of these biological processes is the key to understanding and controlling male fertility. Comparative studies between several epididymal maturation states could be an informative approach to finding sperm modifications related to maturation and fertility. Here we show the data from differential peptidomic/proteomic analyses on spermatozoa isolated from 4 epididymal regions (immature to mature stage) using a profiling approach based on MALDI-TOF mass spectrometry and, combined to top-down MS in order to identify peptidoforms and proteoforms. By this way, 172m/z peaks ranging between 2 and 20 kDa were found to be modified du
