P4ha3 - prolyl 4-hydroxylase subunit alpha 3

Enables procollagen-proline 4-dioxygenase activity. Predicted to be involved in peptidyl-proline hydroxylation to 4-hydroxy-L-proline. Predicted to be located in endoplasmic reticulum lumen. Predicted to be part of procollagen-proline 4-dioxygenase complex. Predicted to be active in endoplasmic reticulum. Orthologous to human P4HA3 (prolyl 4-hydroxylase subunit alpha 3).
