Predicted to enable identical protein binding activity and procollagen-proline 4-dioxygenase activity. Predicted to be involved in peptidyl-proline hydroxylation to 4-hydroxy-L-proline. Predicted to act upstream of or within collagen fibril organization. Predicted to be located in mitochondrion. Predicted to be part of procollagen-proline 4-dioxygenase complex. Predicted to be active in endoplasmic reticulum. Orthologous to human P4HA1 (prolyl 4-hydroxylase subunit alpha 1). [provided by Alliance of Genome Resources, Apr 2022]
