Predicted to enable serine-type endopeptidase activity. Predicted to be involved in positive regulation of acrosome reaction; positive regulation of fertilization; and regulation of protein processing. Predicted to act upstream of or within binding activity of sperm to zona pellucida; cell migration; and protein maturation. Predicted to be active in acrosomal vesicle. Orthologous to human PRSS37 (serine protease 37). [provided by Alliance of Genome Resources, Apr 2022]
