title: Characterization and biological roles of oviduct-specific, oestrogen-dependent glycoprotein.
abstract: During late follicular growth, oestrus, fertilization and early embryonic development, the oviduct, under specific hormonal control, produces fluid and contributes secretory macromolecules that optimize the microenvironment for gamete maturation and transport, fertilization and early cleavage-stage embryonic development. This review describes the state of knowledge concerning the physiological and biochemical characterization of the major oviduct secreted protein, the oviduct-specific, oestrogen-dependent glycoprotein. The identification, localization within the oviduct, binding and association with oocytes, embryos and spermatozoa, hormonal control of gene expression, cloning, gene organization, protein sequences and post-translational modifications of oviduct-specific, oestrogen-dependent glycoprotein are discussed. Identification of biological functions for this glycoprotein, its interactions with spermatozoa, oocytes and embryos and its potential as a paracrine regulator of fertilization and development are also discussed.
