Summary: Enables GTP cyclohydrolase I activity. Involved in positive regulation of heart rate. Acts upstream of or within regulation of lung blood pressure. Predicted to be located in several cellular components, including cytosol; mitochondrion; and nucleus. Predicted to be part of protein-containing complex. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study BH4-deficient hyperphenylalaninemia B. Human ortholog(s) of this gene implicated in several diseases, including BH4-deficient hyperphenylalaninemia B; diabetic angiopathy; movement disease (multiple); sickle cell anemia; and type 2 diabetes mellitus. Orthologous to human GCH1 (GTP cyclohydrolase 1). [provided by Alliance of Genome Resources, Dec 2024]

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.
