Predicted to enable L-ascorbic acid binding activity; iron ion binding activity; and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen. Is an ortholog of C. elegans dpy-18. In C. elegans, dpy-18 is involved in several processes, including cuticle development involved in collagen and cuticulin-based cuticle molting cycle; embryo development; and embryonic body morphogenesis.
