ID:NOXO1_HUMAN DESCRIPTION: RecName: Full=NADPH oxidase organizer 1; AltName: Full=NADPH oxidase regulatory protein; AltName: Full=Nox organizer 1; AltName: Full=Nox-organizing protein 1; AltName: Full=SH3 and PX domain-containing protein 5; 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. SUBUNIT: Interacts with NOX1, NOXA1, CYBA/p22phox and NCF2/p67phox. Interacts with SH3PXD2A and SH3PXD2B. SUBCELLULAR LOCATION: Isoform 3: Cell membrane; Peripheral membrane protein; Cytoplasmic side. Note=Isoform 3 associates with the plasma membrane in a lipid-dependent manner. 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. DEVELOPMENTAL STAGE: Isoform 3 is expressed in fetal liver. DOMAIN: The PX domain mediates lipid-binding, localization to the plasma membrane and is required for NOX1 activation. DOMAIN: The SH3 domains mediate interaction with CYBA/p22phox. Also mediates intramolecular interaction with the proline-rich region. SIMILARITY: Contains 1 PX (phox homology) domain. SIMILARITY: Contains 2 SH3 domains.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
