This protein enables 6 target(s):

TargetCategoryDefinition
iron ion bindingmolecular functionBinding to an iron (Fe) ion. [GOC:ai]
calcium ion bindingmolecular functionBinding to a calcium ion (Ca2+). [GOC:ai]
2-oxoglutarate-dependent dioxygenase activitymolecular functionCatalysis of the reaction: A + 2-oxoglutarate + O2 = B + succinate + CO2. This is an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from 2-oxoglutarate and one other donor, and one atom of oxygen is incorporated into each donor. [GOC:mah]
L-ascorbic acid bindingmolecular functionBinding to L-ascorbic acid, (2R)-2-[(1S)-1,2-dihydroxyethyl]-4-hydroxy-5-oxo-2,5-dihydrofuran-3-olate; L-ascorbic acid is vitamin C and has co-factor and anti-oxidant activities in many species. [GOC:mah]
hypoxia-inducible factor-proline dioxygenase activitymolecular functionCatalysis of the reaction: 2-oxoglutarate + L-prolyl-[hypoxia-inducible factor alpha subunit] + O2 = CO2 + succinate + trans-4-hydroxy-L-prolyl-[hypoxia-inducible factor alpha subunit]. [PMID:11595184, PMID:11598268]
procollagen-proline 4-dioxygenase activitymolecular functionCatalysis of the reaction: procollagen L-proline + 2-oxoglutarate + O2 = procollagen trans-4-hydroxy-L-proline + succinate + CO2. [EC:1.14.11.2]

TargetCategoryDefinition
endoplasmic reticulum membranecellular componentThe lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah]

Active In

This protein is active in 1 target(s):

TargetCategoryDefinition
endoplasmic reticulumcellular componentThe 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]
