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.
