Recombinant Human NADPH oxidase organizer 1 (NOXO1)

Uniprot Id

Q8NFA2

Target Species

Human

Target Name

NOXO1

Target Full Name

NADPH oxidase organizer 1

Target Function

Constitutively potentiates the superoxide-generating activity of NOX1 and NOX3 and is required for the biogenesis of otoconia/otolith, which are crystalline structures of the inner ear involved in the perception of gravity. Isoform 3 is more potent than isoform 1 in activating NOX3. Together with NOXA1, may also substitute to NCF1/p47phox and NCF2/p67phox in supporting the phagocyte NOX2/gp91phox superoxide-generating activity.

Target Subcellular Location

[Isoform 3]: Cell membrane; Peripheral membrane protein; Cytoplasmic side. Note=Isoform 3 associates with the plasma membrane in a lipid-dependent manner (PubMed:12716910).

Target Tissue Specificity

Expressed in testis, small and large intestines, liver, kidney and pancreas. Isoform 3 is mainly expressed in colon. Isoform 1 is preferentially expressed in testis.

Target Synonyms

NADPH oxidase organizer 1; NADPH oxidase regulatory protein; Nox organizer 1; Nox organizing protein 1; Nox-organizing protein 1; NOXO1; NOXO1_HUMAN; P41NOX; Regulatory protein P41NOX; SH3 and PX domain-containing protein 5; SH3PXD5

Target Background

This gene encodes an NADPH oxidase (NOX) organizer, which positively regulates NOX1 and NOX3. The protein contains a PX domain and two SH3 domains. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
