Previous HGNC Symbols for P3H2 Gene
This gene encodes a member of the prolyl 3-hydroxylase subfamily of 2-oxo-glutarate-dependent dioxygenases. These enzymes play a critical role in collagen chain assembly, stability and cross-linking by catalyzing post-translational 3-hydroxylation of proline residues. Mutations in this gene are associated with nonsyndromic severe myopia with cataract and vitreoretinal degeneration, and downregulation of this gene may play a role in breast cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]
GeneCards Summary for P3H2 Gene
P3H2 (Prolyl 3-Hydroxylase 2) is a Protein Coding gene. Diseases associated with P3H2 include Myopia, High, With Cataract And Vitreoretinal Degeneration and Rare Isolated Myopia. Among its related pathways are Collagen chain trimerization and Degradation of the extracellular matrix.

An important paralog of this gene is P3H1.
UniProtKB/Swiss-Prot Summary for P3H2 Gene
Prolyl 3-hydroxylase that catalyzes the post-translational formation of 3-hydroxyproline on collagens (PubMed:18487197). Contributes to proline 3-hydroxylation of collagen COL4A1 and COL1A1 in tendons, the eye sclera and in the eye lens capsule (By similarity). Has high activity with the type IV collagen COL4A1, and lower activity with COL1A1 (PubMed:18487197). Catalyzes hydroxylation of the first Pro in Gly-Pro-Hyp sequences where Hyp is 4-hydroxyproline (PubMed:18487197). Has no activity on substrates that lack 4-hydroxyproline in the third position (PubMed:18487197).
