Loss of the deglutamylase CCP5 perturbs multiple steps of spermatogenesis and leads to male infertility

Abstract excerpt

Sperm cells are highly specialized mammalian cells, and their biogenesis requires unique intracellular structures. Perturbation of spermatogenesis often leads to male infertility. Here, we assess the role of a post-translational modification of tubulin, glutamylation, in spermatogenesis. We show that mice lacking the tubulin deglutamylase CCP5 (also known as AGBL5) do not form functional sperm. In these mice,...
