Summary: Enables GTP cyclohydrolase I activity. Involved in dopamine biosynthetic process from tyrosine; melanin biosynthetic process; and tetrahydrobiopterin biosynthetic process. Predicted to be active in cytoplasm. Is expressed in several structures, including body wall musculature; dopaminergic neurons; hyp7 syncytium; intestinal cell; and serotonergic neurons. 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]
