EOG8SJ7WF GO:0016491 61/186 oxidoreductase activity molecular_function "Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced." [GOC:go_curators] EOG8SJ7WF GO:0004303 2/186 estradiol 17-beta-dehydrogenase activity molecular_function "Catalysis of the reaction: estradiol-17-beta + NADP+ = estrone + NADPH + H+." [EC:1.1.1.62] EOG8SJ7WF GO:0006909 1/186 phagocytosis biological_process "An endocytosis process that results in the engulfment of external particulate material by phagocytes. The particles are initially contained within phagocytic vacuoles (phagosomes), which then fuse with primary lysosomes to effect digestion of the particles." [ISBN:0198506732] EOG8SJ7WF GO:0005783 1/186 endoplasmic reticulum cellular_component "The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached)." [ISBN:0198506732] EOG8SJ7WF GO:0008285 1/186 negative regulation of cell proliferation biological_process "Any process that stops, prevents or reduces the rate or extent of cell proliferation." [GOC:go_curators] EOG8SJ7WF GO:0007030 1/186 Golgi organization biological_process "A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the Golgi apparatus."
