Abstract

Sepiapterin reductase (SPR) is an enzyme that acts in the third and final step of tetrahydrobiopterin (BH4) biosynthesis. The human Spr gene locates within the region of 2.5MB mapped to PARK3, an autosomal dominant form of familial Parkinson's diseases. In order to explore the role of SPR in the metabolism of BH4, we produced and analyzed Spr-deficient mice. Most of Spr-null mice survived beyond two weeks. Whereas the BH4 contents in the homozygous mutant mice were greatly decreased than those in wild-type and heterozygous mice, the substantial amounts of BH4 were remained even 17 days after delivery. Spr-null mice exhibited severe monoamine deficiencies and a tremor-like phenotype after weaning. The amount of TH protein in the brain of Spr-null mice was less than 10% of wild-type, while TH protein in the adrenal, phenylalanine hydroxylase protein in the liver, and nNOS in the brain were not altered. These data suggest an essential role of SPR in the biosynthesis of BH4, and that the SPR gene could be a candidate gene for PARK3.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
