Eppin - epididymal peptidase inhibitor

Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in several processes, including negative regulation of calcium ion import; negative regulation of flagellated sperm motility; and negative regulation of peptidase activity. Predicted to be located in acrosomal vesicle and cell surface. Predicted to be part of protein-containing complex. Predicted to be active in extracellular space. Orthologous to several human genes including EPPIN-WFDC6 (EPPIN-WFDC6 readthrough). [provided by Alliance of Genome Resources, Apr 2022]
