Quinonoid dihydropteridine reductase (QDPR) catalyzes the regeneration of tetrahydrobiopterin (BH4), a cofactor for monoamine synthesis, phenylalanine hydroxylation and nitric oxide production. Here, we produced and analyzed a transgenic Qdpr (/) ...
Background: Loss of adenomatous polyposis coli (APC) gene function results in constitutive activation of the canonical Wnt pathway and represents the main initiating and rate-limiting event in colorectal tumorigenesis. APC is likely to participate...
Phenylketonuria (PKU) is a common genetic disorder arising from a deficiency of phenylalanine hydroxylase. If left untreated, the accumulation of phenylalanine leads to brain damage and neuropsychological dysfunction. One of the abnormalities foun...

The tyrosine hydroxylase (TH; EC 1.14.16.2) is a rate-limiting enzyme in the dopamine synthesis and important for the central dopaminergic system, which controls voluntary movements and reward-dependent behaviors. Here, to further explore the regu...

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...
