From: Dual roles for ubiquitination in the processing of sperm organelles after fertilization
Spermatozoa contain proteasomes. Proteasome antibody (red), 1CB4 (green), and DAPI (blue) were used to stain mature sperm from C. elegans hermaphrodites. DIC images are shown on the bottom. Three sperm are in the left panel and a single sperm is shown in the right panel. Proteasomes and MOs (1CB4) show minimal overlap. Proteasomes are often found localized to a region between the cell body and the pseudopod (see sperm on right).
