Predicted to be a structural constituent of collagen and cuticulin-based cuticle. Involved in cuticle development involved in collagen and cuticulin-based cuticle molting cycle. Located in medial layer of collagen and cuticulin-based cuticle extracellular matrix. Expressed in cuticle;
hyp7 syncytium; and seam cell. Human ortholog(s) of this gene implicated in Stickler syndrome and multiple epiphyseal dysplasia 6. Is an ortholog of human COL27A1 (collagen type XXVII alpha 1 chain) and COL9A1 (collagen type IX alpha 1 chain).
