Protein

Dual oxidase 1

Gene

DUOX1

Organism
Canis lupus familiaris (Dog) (Canis familiaris)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

NAD(P)H + O2 = NAD(P)+ + H2O2.1 Publication

Enzyme regulationi

Peroxidase activity is inhibited by aminobenzohydrazide (By similarity). The NADPH oxidase activity is calcium-dependent.By similarity1 Publication

Pathwayi: thyroid hormone biosynthesis

This protein is involved in the pathway thyroid hormone biosynthesis, which is part of Hormone biosynthesis.
View all proteins of this organism that are known to be involved in the pathway thyroid hormone biosynthesis and in Hormone biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
