Rabbit anti-Human DUOX1 Polyclonal Antibody

Uniprot Id

Q9NRD9

Target Species

Human

Target Name

DUOX1

Target Full Name

Dual oxidase 1

Target Function

Generates hydrogen peroxide which is required for the activity of thyroid peroxidase/TPO and lactoperoxidase/LPO. Plays a role in thyroid hormones synthesis and lactoperoxidase-mediated antimicrobial defense at the surface of mucosa. May have its own peroxidase activity through its N-terminal peroxidase-like domain.

Target Subcellular Location

Apical cell membrane; Multi-pass membrane protein. Note=Localizes to the apical membrane of epithelial cells.

Target Protein Families

Peroxidase family

Target Tissue Specificity

Expressed in thyrocytes and tracheal surface epithelial cells (at protein level). Expressed in thyroid, trachea, bronchium, and to a lower extent, in placenta, testis, prostate, pancreas and heart.

Target Synonyms

DUOX1; DUOX; LNOX1; THOX1Dual oxidase 1; EC 1.11.1.-; EC 1.6.3.1; Large NOX 1; Long NOX 1; NADPH thyroid oxidase 1; Thyroid oxidase 1

Target Background

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.
