Description
Predicted to have GTP binding activity; GTP cyclohydrolase I activity; and zinc ion binding activity. Involved in xanthophore differentiation. Predicted to localize to cytoplasm. Is expressed in head; neural crest; pigment cell; trunk; and xanthoblast. Human ortholog(s) of this gene implicated in bipolar disorder; dystonia; and dystonia 5. Orthologous to human GCH1 (GTP cyclohydrolase 1).
