Predicted to enable procollagen-proline 3-dioxygenase activity. Acts upstream of or within collagen fibril organization; negative regulation of cell growth; and regulation of ossification. Predicted to be located in basement membrane; cytoplasm; and nucleus. Predicted to be active in endoplasmic reticulum. Is expressed in several structures, including alimentary system; genitourinary system; limb mesenchyme; sensory organ; and skeleton. Used to study osteogenesis imperfecta type 8. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 8. Orthologous to human P3H1 (prolyl 3-hydroxylase 1). [provided by Alliance of Genome Resources, Apr 2022]
