This gene encodes an enzyme that is a member of the collagen prolyl hydroxylase family. These enzymes are localized to the endoplasmic reticulum and their activity is required for proper collagen synthesis and assembly. Mutations in this gene are associated with osteogenesis imperfecta type VIII. Three alternatively spliced transcript variants encoding different isoforms have been described. Other variants may exist, but their biological validity has not been determined. [provided by RefSeq, Aug 2011]

A study in human menstrual blood-derived mesenchymal stem cells (MenSCs) identified the P3H1 as a protein involved in extracellular matrix organization within a protein-protein interaction network, though it was not listed as differentially expressed using the applied fold-change cut-off in the proteomic analysis [Penariol et al. DOI:10.3390/ijms231911515].
