Probable cuticular collagen-like protein (Probable). Nematode cuticles are composed largely of collagen-like proteins (Probable). The cuticle functions both as an exoskeleton and as a barrier to protect the worm from its environment (Probable). Acts downstream of the Wnt signaling pathway, perhaps in the formation of the adult cuticle (PubMed:24569038). Collagen polypeptide chains are complexed within the cuticle by disulfide bonds and other types of covalent cross-links. Expressed in hypodermal cells and seam cells, in the larval L4 stage, and in the young adult (PubMed:24569038). Not expressed in the cells of the developing vulva (PubMed:24569038). RNAi-mediated knockdown causes hypodermal or cuticular rupture, typically in the anterior body region (PubMed:24569038). Dumpy body shape (PubMed:24569038). Defects in cuticle integrity (PubMed:24569038). Belongs to the cuticular collagen family.
