Predicted to enable iron ion binding activity and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced pteridine as one donor, and incorporation of one atom of oxygen. Predicted to be involved in aromatic amino acid metabolic process. Is an ortholog of C. elegans
tph-1. In C. elegans,
tph-1 is involved in several processes, including determination of adult lifespan; locomotory exploration behavior; and positive regulation of transforming growth factor beta receptor signaling pathway.
