Theoretical Model(hide GO term definitions)
Chain A,B   (RELX_PIG | P01348)
molecular function
    GO:0005179    hormone activity    The action characteristic of a hormone, any substance formed in very small amounts in one specialized organ or group of cells and carried (sometimes in the bloodstream) to another organ or group of cells in the same organism, upon which it has a specific regulatory action. The term was originally applied to agents with a stimulatory physiological action in vertebrate animals (as opposed to a chalone, which has a depressant action). Usage is now extended to regulatory compounds in lower animals and plants, and to synthetic substances having comparable effects; all bind receptors and trigger some biological process.
biological process
    GO:0001832    blastocyst growth    An increase in size of a blastocyst due to expansion of the blastocoelic cavity cell shape changes and cell proliferation.
    GO:0030317    flagellated sperm motility    Any process involved in the controlled movement of a flagellated sperm cell.
    GO:0001556    oocyte maturation    A developmental process, independent of morphogenetic (shape) change, that is required for an oocyte to attain its fully functional state. Oocyte maturation commences after reinitiation of meiosis commonly starting with germinal vesicle breakdown, and continues up to the second meiotic arrest prior to fertilization.
    GO:2000344    positive regulation of acrosome reaction    Any process that activates or increases the frequency, rate or extent of the acrosome reaction.
    GO:0050679    positive regulation of epithelial cell proliferation    Any process that activates or increases the rate or extent of epithelial cell proliferation.
    GO:0046326    positive regulation of glucose import    Any process that activates or increases the frequency, rate or extent of the import of the hexose monosaccharide glucose into a cell or organelle.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
