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.
  • Target information above from: UniProt accession P35270 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .

      ab157194 Anti-SPR antibody [EPR9290] was shown to specifically react with SPR in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264681 (knockout cell lysate ab258700) was used. Wild-type and SPR knockout samples were subjected to SDS-PAGE. ab157194 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.
