Enables sterol transporter activity. Involved in several processes, including ecdysis, collagen and cuticulin-based cuticle; nematode larval development; and regulation of locomotion. Located in apical plasma membrane and endocytic vesicle. Expressed in head;
hyp6;
hyp7 syncytium; and hypodermal cell. Human ortholog(s) of this gene implicated in Donnai-Barrow syndrome and autoimmune thyroiditis. Is an ortholog of human LRP2 (LDL receptor related protein 2).
