SPR

This gene encodes an aldo-keto reductase that catalyzes the NADPH-dependent reduction of pteridine derivatives and is important in the biosynthesis of tetrahydrobiopterin (BH4). Mutations in this gene result in DOPA-responsive dystonia due to sepiaterin reductase deficiency. A pseudogene has been identified on chromosome 1. [provided by RefSeq, Jul 2008]
Full Name
Sepiapterin Reductase
Function
Catalyzes the final one or two reductions in tetra-hydrobiopterin biosynthesis to form 5,6,7,8-tetrahydrobiopterin.
Biological Process
Biological Process nitric oxide biosynthetic processManual Assertion Based On ExperimentIDA:UniProtKB

Involvement in disease
Dystonia, DOPA-responsive, due to sepiapterin reductase deficiency (DRDSPRD):
A form of DOPA-responsive dystonia. In the majority of cases, patients manifest progressive psychomotor retardation, dystonia and spasticity. Cognitive anomalies are also often present. The disease is due to severe dopamine and serotonin deficiencies in the central nervous system caused by a defect in BH4 synthesis. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures.
PTM
In vitro phosphorylation of Ser-213 by CaMK2 does not change kinetic parameters.
