Target

  • Function
    Catalyzes the final one or two reductions in tetra-hydrobiopterin biosynthesis to form 5,6,7,8-tetrahydrobiopterin.
  • Involvement in disease
    Defects in SPR are the cause of dystonia DOPA-responsive due to sepiapterin reductase deficiency (DRDSPRD) [MIM:612716]. 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.
  • Sequence similarities
    Belongs to the sepiapterin reductase family.
  • Post-translational
    modifications
    In vitro phosphorylation of Ser-213 by CaMK2 does not change kinetic parameters.
  • Cellular localization
    Cytoplasm.
  • Information by UniProt
  • Database links
  • Alternative names
    • OTTHUMP00000160199 antibody
    • SDR38C1 antibody
    • Sepiapterin reductase (7,8 dihydrobiopterin:NADP+ oxidoreductase) antibody
    • Sepiapterin reductase antibody
    • Short chain dehydrogenase/reductase family 38C, member 1 antibody
