Predicted to enable metal ion binding activity and serine-type endopeptidase activity. Involved in positive regulation of fertilization. Acts upstream of or within binding activity of sperm to zona pellucida; cell migration; and protein maturation. Predicted to be located in cytoplasmic vesicle and extracellular region. Predicted to be active in acrosomal vesicle. Orthologous to human PRSS37 (serine protease 37). [provided by Alliance of Genome Resources, Apr 2022]
