Oviduct-specific glycoprotein also known as oviductal glycoprotein (OGP) or estrogen-dependent oviduct protein (EGP) or mucin-9 (MUC9) is a protein that in humans is encoded by the OVGP1gene.[1][2][3]
Function
Oviduct-specific glycoprotein is a large, carbohydrate-rich, epithelialglycoprotein with numerous O-glycosylation sites located within threonine, serine, and proline-rich tandem repeats. The gene is similar to members of the mucin and the glycosyl hydrolase 18 gene families. Regulation of expression may be estrogen-dependent. Gene expression and protein secretion occur during late follicular development through early cleavage-stage embryonic development. The protein is secreted from non-ciliated oviductal epithelial cells and associates with ovulated oocytes, blastomeres, and spermatozoon acrosomal regions.[3]
