Protein Information
Function Glycoprotein that regulates critical steps during fertilization and also has immunomonomodulatory effects. Four glycoforms, namely glycodelin-S, -A, -F and -C have been identified in reproductive tissues that 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). Glycodelin-F inhibits spermatozoa- zona pellucida binding and significantly suppresses progesterone- induced acrosome reaction of spermatozoa (PubMed:12672671). Glycodelin-S in seminal plasma maintains the uncapacitated state of human spermatozoa (PubMed:15883155).
Cellular Location Secreted
Tissue Location This protein is, the main protein synthesized and secreted in the endometrium from mid-luteal phase of the menstrual cycle and during the first semester of pregnancy (PubMed:3667877). Glycodelin-A is expressed in amniotic fluid, endometrium/decidua and maternal serum (at protein level) (PubMed:3194393). Glycodelin-F is expressed in follicular fluid, luteinized granulosa cells and the oviduct (at protein level) (PubMed:12672671). Glycodelin-S is expressed in seminal plasma and seminal vesicles (at protein level) (PubMed:9239694). Glycodelin-C is detected in cumulus cells (at protein level), but cumulus cells do not synthesize Glycodelin-C but take up and convert glycodelin- A and -F vis glycan remodeling (PubMed:17192260)

PAEP (Progesterone-associated endometrial protein, glycodelin, PEG, PP14) is a glycoprotein belonging to lipocalin structural superfamily. It shares a sequence homology to beta-lactoglobulins containing a retinol-binding motif and it is mainly produced by secretory and decidualized endometrium in women and by seminal vesicle epithelium in men (1). PAEP function is not clearly understood. However, glycosylated version of PAEP (GdA) has been associated to contraceptive and immunosuppressive activities during reproduction. PAEP is the main protein produced by secretory endometrium during mid-luteal phase of the menstrual cycle and during the first semester of pregnancy. Therefore, PAEP has been linked as an ideal biomarker of endometrial activity and function for in vitro fertilization treated women (2).
