Glycodelin (PAEP)

Glycoprotein that regulates critical steps during fertilization and has immunomonomodulatory effects. Four glycoforms, namely glycodelin-S, -A, -F and -C have been identified in reproductive cells which differ in glycosylation and biological activity.

Glycodelin-A has contraceptive and immunosuppressive activities (PubMed:9918684, PubMed:7531163). Glycodelin-C stimulates binding of spermatozoa to the zona pellucida (PubMed:17192260).
