| Function |
Oocyte-specific oolemmal receptor involved in sperm and egg adhesion and fertilization. Plays a role in the polyspermy inhibition. Probably acts as a protease for the post-fertilization cleavage of ZP2. Cleaves the sperm-binding ZP2 at the surface of the zona pellucida after fertilization and cortical granule exocytosis, rendering the zona pellucida unable to support further sperm binding (By similarity). {ECO:0000250}.

| Subcellular Location |
Cytoplasm {ECO:0000250}. Cell membrane {ECO:0000250}. Cytoplasmic granule {ECO:0000250}. Cytoplasmic vesicle, secretory vesicle {ECO:0000250}. Note=Secretory granules. Localizes to the peripheral cortical granules of ovulated eggs. Probably exocytosed from cortical granules during post- fertilization. Detected throughout the ooplasm of germinal vesicle stage oocytes in early bilaminar secondary follicles shortly after birth. Detected in the microvillar domain of the oolemma in arrested ovulated secondary oocytes and in the first polar body prior to fertilization. Upon fertilization, detected in the perivitelline space (PVS). Colocalizes with SPACA3 at the microvillar domain of the oolemma and in the perivitelline space (PVS) (By similarity). {ECO:0000250}.

| Tissue Specificity |
Expressed in promyelocytic leukemia HL-60 cells, Burkitt's lymphoma Raji cells, and also in some ovarian carcinomas. Not detected in normal tissues. {ECO:0000269|PubMed:15087446}.
