P4ha2 - procollagen-proline, 2-oxoglutarate 4-dioxygenase (proline 4-hydroxylase), alpha II polypeptide

Enables procollagen-proline 4-dioxygenase activity. Acts upstream of or within peptidyl-proline hydroxylation to 4-hydroxy-L-proline. Part of procollagen-proline 4-dioxygenase complex. Is expressed in alimentary system; pectoral girdle and thoracic body wall musculature; and skeleton. 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]
