Centrioles are microtubule-based, barrel-shaped, subcellular organelles with evolutionarily conserved composition, structure, and function. Yet, in sperm cells, centrioles are remodeled, gaining species-specific composition and structure. The sperm centrioles of undergo dramatic remodeling, during which most known centriolar proteins are lost. Here, we find that . This labeling offers a simple method for marking the spermatozoan centriole, though it may interfere with testing new anti-centriolar antibodies using immunofluorescence.
