Uncovering the protein complex critical to male fertility

Researchers found that TEX38 and ZDHHC19 co-localize on the plasma membrane of spermatids and mediate S-palmitoylation of ARRDC5, a crucial protein for spermatogenesis. Disrupting either TEX38 or ZDHHC19 inhibited cytoplasm removal from the sperm head, resulting in deformed sperm and infertility in a male mouse model.
