Predicted to be a structural constituent of cuticle. Predicted to be part of collagen trimer. Is an ortholog of human COL21A1 (collagen type XXI alpha 1 chain).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
