Protein existence	Evidence at protein level

General annotation (Comments)

Function	Catalyzes the post-translational formation of 4-hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins. Ref.1 Ref.2
Catalytic activity	L-proline-[procollagen] + 2-oxoglutarate + O2 = trans-4-hydroxy-L-proline-[procollagen] + succinate + CO2.
Cofactor	Binds 1 Fe2+ ion per subunit. Ascorbate.
Subunit structure	Heterotetramer of two alpha-3 chains and two beta chains (the beta chain is the multi-functional PDI). Ref.1 Ref.2
Subcellular location	Endoplasmic reticulum lumen Probable.
Tissue specificity	Highly expressed in placenta, liver and fetal skin. Weakly expressed in fetal epiphyseal cartilage, fetal liver, fibroblast, lung and skeletal muscle. Expressed also in fibrous cap of carotid atherosclerotic lesions. Ref.1 Ref.2
Post-translational modification	N-glycosylation plays no role in the catalytic activity.
Sequence similarities	Belongs to the P4HA family. Contains 1 Fe2OG dioxygenase domain. Contains 1 TPR repeat.
