Recombinant Human Phytanoyl-CoA dioxygenase, peroxisomal (PHYH)

Uniprot Id

O14832

Target Species

Human

Target Name

PHYH

Target Full Name

Phytanoyl-CoA dioxygenase, peroxisomal

Target Function

Catalyzes the 2-hydroxylation of not only racemic phytanoyl-CoA and the isomers of 3-methylhexadecanoyl-CoA, but also a variety of other mono-branched 3-methylacyl-CoA esters (with a chain length of at least seven carbon atoms) and straight-chain acyl-CoA esters (with a chain length longer than four carbon atoms). Does not hydroxylate long and very long straight chain acyl-CoAs or 2-methyl- and 4-methyl-branched acyl-CoAs.

Target Involvement

Refsum disease (RD)

Target Subcellular Location

Peroxisome.

Target Protein Families

PhyH family

Target Tissue Specificity

Expressed in liver, kidney, and T-cells, but not in spleen, brain, heart, lung and skeletal muscle.

Target Research Area

Signal Transduction

Target Background

This gene is a member of the PhyH family and encodes a peroxisomal protein that is involved in the alpha-oxidation of 3-methyl branched fatty acids. Specifically, this protein converts phytanoyl-CoA to 2-hydroxyphytanoyl-CoA. Mutations in this gene have been associated with Refsum disease (RD) and deficient protein activity has been associated with Zellweger syndrome and rhizomelic chondrodysplasia punctata. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
