SummaryCells express different gene products in order to achieve specialization and differentiation. Sperm are highly specialized to do nothing more than fertilize an oocyte, and they are thus an excellent candidate for research into cellular specialization.1 A terminally differentiated cell like a spermatozoa is useful to study protein composition, because it has a relatively small number of proteins designed to carry out a limited amount of tasks, namely fertilization. Spermatozoa are useful models to study cytoskeleton-dependent motility because their tails, containing the microtubule array necessary for movement, can easily be separated from their heads, which have microtubules for structure and scaffolding rather than motility. Thus, the protein composition of these two sections can make useful comparisons in the study of motility-associated cytoskeleton versus non-motility-associated cytoskeleton.
