Predicted to enable procollagen-proline 4-dioxygenase activity. Predicted to be involved in peptidyl-proline hydroxylation to 4-hydroxy-L-proline. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of procollagen-proline 4-dioxygenase complex. Predicted to be active in endoplasmic reticulum. Human ortholog(s) of this gene implicated in myopia. Orthologous to human P4HA2 (prolyl 4-hydroxylase subunit alpha 2). [provided by Alliance of Genome Resources, Apr 2022]
