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
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).
