Enzyme Function FUNCTION: As a strong inhibitor of acrosin, it is required for normal spermiogenesis. It probably hinders premature activation of proacrosin and other proteases, thus preventing the cascade of events leading to spermiogenesis defects. May be involved in the regulation of serine protease-dependent germ cell apoptosis. It also inhibits trypsin. {ECO:0000250|UniProtKB:Q8BMY7}.
