Summary: Enables protein homodimerization activity. Acts upstream of or within several processes, including L-phenylalanine metabolic process; catecholamine metabolic process; and voluntary musculoskeletal movement. Located in mitochondrion. Is expressed in several structures, including alimentary system; heart; nervous system; sensory organ; and skeleton. Used to study Parkinson's disease. Human ortholog(s) of this gene implicated in dystonia and sepiapterin reductase deficiency. Orthologous to human SPR (sepiapterin reductase). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Our results suggest that the hypertension with fluctuation and bradycardia of Spr(-/-) mice would be caused by an imbalance of sympathetic and parasympathetic input and impaired nitric oxide production in endothelial cells.
Title: Sepiapterin reductase gene-disrupted mice suffer from hypertension with fluctuation and bradycardia.
SPR-mediated reduction of sepiapterin and redox cycling occur by distinct mechanisms
Title: Sepiapterin reductase mediates chemical redox cycling in lung epithelial cells.
biopterin contents in the brains of these knock-out mice were moderately decreased from postnatal day 0 (P0) and remained constant up to P21
Title: Partial biopterin deficiency disturbs postnatal development of the dopaminergic system in the brain.
These data suggest an essential role of SPR in the biosynthesis of BH4, and that the SPR gene could be a candidate gene for PARK3.
Title: A brain-specific decrease of the tyrosine hydroxylase protein in sepiapterin reductase-null mice--as a mouse model for Parkinson's disease.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
