MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a glycoprotein and a member of the NADPH oxidase family. The synthesis of thyroid hormone is catalyzed by a protein complex located at the apical membrane of thyroid follicular cells. This complex contains an iodide transporter, thyroperoxidase, and a peroxide generating system that includes proteins encoded by this gene and the similar DUOX2 gene. This protein is known as dual oxidase because it has both a peroxidase homology domain and a gp91phox domain. This protein generates hydrogen peroxide and thereby plays a role in the activity of thyroid peroxidase, lactoperoxidase, and in lactoperoxidase-mediated antimicrobial defense at mucosal surfaces. Two alternatively spliced transcript variants encoding the same protein have been described for this gene. [provided by RefSeq, Jul 2012]

Nature of Mutation
DNA sequencing using the SOLiD technique identified a G to A transition at position 4104 of the Duox1 transcript in exon 29 of 33 total exons.  The mutated nucleotide causes a cysteine to tyrosine substitution at amino acid 1358 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Duox1 gene encodes a 1551 amino acid oxidoreductase that is involved in the synthesis of thyroid hormone (Uniprot A2AQ92).  As predicted by SMART, the protein contains several domains including an N-terminal ferric oxidoreductase domain, followed by a transmembrane domain, two calcium-binding EF hands, and C-terminal FAD (flavin adenine dinucleotide)- and NAD (nicotinamide adenine dinucleotide)-binding domains.
 
The C1358Y change is located in the FAD-binding domain, and is predicted to be benign by the PolyPhen program.
