duox-2 encodes a large partial homolog of dual oxidase, with an N-terminal peroxidase domain, two central calmodulin-binding EF hands, and a C-terminal superoxide-generating NADPH-oxidase domain; duox-2 may be required for dityrosine cross-linking of collagen, and thus for cuticular integrity; duox-2 may use cytosolic NADPH to generate reactive oxygen, which then may drive the peroxidase ectodomain to cross-link free tyrosine in collagen; DUOX-2 has no visible expression pattern detectable by antibodies, implying very low or rare expression.
Predicted to enable superoxide-generating NAD(P)H oxidase activity. Involved in cuticle development involved in collagen and cuticulin-based cuticle molting cycle and post-embryonic body morphogenesis. Predicted to be located in plasma membrane. Predicted to be part of NADPH oxidase complex. Human ortholog(s) of this gene implicated in cholera; inflammatory bowel disease (multiple); and thyroid dyshormonogenesis 6. Is an ortholog of human DUOX2 (dual oxidase 2).
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.
