General annotation (Comments)
| Function | Functions as an activator of NOX1, a superoxide-producing NADPH oxidase. Functions in the production of reactive oxygen species (ROS) which participate in a variety of biological processes including host defense, hormone biosynthesis, oxygen sensing and signal transduction. May also activate CYBB/gp91phox and NOX3. Ref.1 Ref.2 Ref.3 Ref.7 Ref.8 Ref.9 Ref.10 Ref.13 Ref.16 |
| Subunit structure | NOX1, NOXA1, NOXO1, RAC1 and CYBA forms a functional multimeric complex supporting ROS production. Interaction with YWHAZ prevents the interaction of NOXA1 with NOXO1 and RAC1 and its targeting to membranes, hence reducing its ability to activate NOX1. Interacts (via N-terminus) with SH3PXD2A and SH3PXD2B; the interaction is direct. Ref.2 Ref.11 Ref.12 Ref.14 Ref.15 Ref.16 Ref.17 |
| Subcellular location | Cytoplasm. Cell membrane. Note: Translocation to membranes depends on NOXO1 or NCF1 and maybe RAC1. Ref.12 Ref.13 |
| Tissue specificity | Widely expressed. Detected in pancreas, liver, kidney, spleen, prostate, small intestine and colon. Ref.2 |
| Developmental stage | Expressed in fetal kidney. Ref.10 |
| Domain | The SH3 domain mediates interaction with NOXO1 and NCF1 and has autoregulatory function. The TPR repeats mediate interaction with RAC1. |
| Post-translational modification | Interaction with YWHAZ depends on phosphorylation by PKA. |
| Sequence similarities | Belongs to the NCF2/NOXA1 family. Contains 1 OPR domain. Contains 1 SH3 domain. Contains 4 TPR repeats. |
| Sequence caution | The sequence AAY16126.1 differs from that shown. Reason: Frameshift at position 305. |

| Isoform 1 (identifier: Q86UR1-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q86UR1-2) The sequence of this isoform differs from the canonical sequence as follows: 431-431: E → EEPDVPLA | ||||||
| Note: Mostly inactive for NOX1 activation. Does not interact with NOXO1. | ||||||
| Isoform 3 (identifier: Q86UR1-3) Also known as: NOXA1inhib; The sequence of this isoform differs from the canonical sequence as follows: 168-223: Missing. 431-431: E → EEPDVPLA | ||||||
| Note: Inactive for NOX1 activation. No experimental confirmation available. |
