| Protein existence | Evidence at transcript level. |
General annotation (Comments)
| Function | Has prolyl 3-hydroxylase activity catalyzing the post-translational formation of 3-hydroxyproline in -Xaa-Pro-Gly-sequences in collagens, especially types IV and V By similarity. |
| Catalytic activity | Procollagen L-proline + 2-oxoglutarate + O2 = procollagen trans-3-hydroxy-L-proline + succinate + CO2. |
| Cofactor | Iron By similarity. Ascorbate By similarity. |
| Subcellular location | |
| Tissue specificity | Expressed in heart, placenta, lung, liver, skeletal muscle and kidney. Expression localized to the epithelia of bile ducts and to the sacroplasm of heart muscle and skeletal muscle. In the pancreas, localized to a subpopulation of Langerhans islet cells and in the salivary gland, expressed in acinar cells. Ref.2 |
| Sequence similarities | Belongs to the leprecan family. Contains 1 PKHD (prolyl/lysyl hydroxylase) domain. Contains 4 TPR repeats. |
