All terms in GO

Label Id Description
response to protozoan GO_0001562 [Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a protozoan.]
obsolete resistance to pathogenic protozoa GO_0001564 [OBSOLETE. (Was not defined before being made obsolete).]
fatty acid alpha-oxidation GO_0001561 [A metabolic pathway by which 3-methyl branched fatty acids are degraded. These compounds are not degraded by the normal peroxisomal beta-oxidation pathway, because the 3-methyl blocks the dehydrogenation of the hydroxyl group by hydroxyacyl-CoA dehydrogenase. The 3-methyl branched fatty acid is converted in several steps to pristenic acid, which can then feed into the beta-oxidative pathway.]
regulation of cell growth by extracellular stimulus GO_0001560 [Any process in which external signals modulate the frequency, rate or extent of cell growth, the irreversible increase in size of a cell over time.]
obsolete regulation of cell growth by detection of nuclear:cytoplasmic ratio GO_0001559 [OBSOLETE. Any process in which the size of the nucleus with respect to the cytoplasm modulates the frequency, rate or extent of cell growth, the irreversible increase in size of a cell over time.]
oocyte maturation GO_0001556 [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.]
obsolete metabolic process resulting in cell growth GO_0001557 [OBSOLETE. The chemical reactions that occur in living organisms that result in an increase in the mass (size) of a cell.]
luteolysis GO_0001554 [The lysis or structural demise of the corpus luteum. During normal luteolysis, two closely related events occur. First, there is loss of the capacity to synthesize and secrete progesterone (functional luteolysis) followed by loss of the cells that comprise the corpus luteum (structural luteolysis). Preventing luteolysis is crucial to maintain pregnancy.]
oocyte growth GO_0001555 [The developmental growth process in which an oocyte irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.]
ovarian follicle atresia GO_0001552 [A periodic process in which immature ovarian follicles degenerate and are subsequently re-absorbed.]
luteinization GO_0001553 [The set of processes resulting in differentiation of theca and granulosa cells into luteal cells and in the formation of a corpus luteum after ovulation.]
ovarian cumulus expansion GO_0001550 [Increase in size of the cumulus surrounding the oocyte including change in morphology due to proliferation and dispersion of cumulus cells.]
ovarian follicle endowment GO_0001551 [Association of oocytes with supporting epithelial granulosa cells to form primordial follicles.]
GO_0001668 GO_0001668
acrosomal vesicle GO_0001669 [A structure in the head of a spermatozoon that contains acid hydrolases, and is concerned with the breakdown of the outer membrane of the ovum during fertilization. It lies just beneath the plasma membrane and is derived from the lysosome.]
alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase activity GO_0001665 [Catalysis of the reaction: CMP-N-acetylneuraminate + glycano-(1->3)-(N-acetyl-alpha-D-galactosaminyl)-glycoprotein = CMP + glycano-[(2->6)-alpha-N-acetylneuraminyl]-(N-acetyl-D-galactosaminyl)-glycoprotein.]
sialyltransferase activity GO_0008373 [Catalysis of the transfer of sialic acid to an acceptor molecule, typically the terminal portions of the sialylated glycolipids (gangliosides) or to the N- or O-linked sugar chains of glycoproteins.]
behavioral fear response GO_0001662 [An acute behavioral change resulting from a perceived external threat.]
fear response GO_0042596 [The response of an organism to a perceived external threat.]
behavioral defense response GO_0002209 [A behavioral response seeking to protect an organism from an perceived external threat to that organism.]
