2,4-Diamino-6-hydroxypyrimidine (DAHP) is considered a specific inhibitor of BH4 biosynthesis and is widely used in order to elucidate the possible biological function of BH4 in various cells. In the present study, we found that both the synthesis...

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 2.5 MB mapped to PARK3, an autosomal dominant form of familial Parkinson's di...

ATF-2/CRE-BP1 was originally identified as a cAMP-responsive element (CRE) binding protein abundant in the brain. We previously reported that phosphorylation of ATF-2 increased the expression of tyrosine hydroxylase (TH), which is the rate-limitin...
(6R)-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) is an essential cofactor for aromatic amino acid hydroxylases, such as phenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH), tryptophan hydroxylase, and nitric oxide synthase, which catalyze p...

One of the possibly mutated genes in DOPA-responsive dystonia (DRD, Segawa's disease) is the gene encoding GTP cyclohydrolase I, which is the rate-limiting enzyme for tetrahydrobiopterin (BH4) biosynthesis. Based on our findings on 6-pyruvoyltetra...

GTP cyclohydrolase I is the first and rate-limiting enzyme for the biosynthesis of tetrahydrobiopterin in mammals. Previously, we reported three species of human GTP cyclohydrolase I cDNA in a human liver cDNA library (Togari, A., Ichinose, H., Ma...

Monkeys are known to be highly susceptible to 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) which produces parkinsonism, as in humans. We have previously reported that only monkeys and humans have multiple isoforms of tyrosine hydroxylase...
