Summaries for P3H2 Gene

Entrez Gene Summary 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 Degradation of the extracellular matrix and Collagen biosynthesis and modifying enzymes. GO annotations related to this gene include oxidoreductase activity and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen. An important paralog of this gene is P3H4.
