Protein existenceEvidence at protein level

General annotation (Comments)

Function

Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets.

Catalytic activity

2 L-arginine + 3 NADPH + 4 O2 = 2 L-citrulline + 2 nitric oxide + 3 NADP+ + 4 H2O.

Cofactor

Heme group.

Binds 1 FAD.

Binds 1 FMN.

Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme.

Enzyme regulation

Stimulated by calcium/calmodulin. Inhibited by NOSIP and NOSTRIN By similarity.

Subunit structure

Homodimer. Interacts with NOSIP and NOSTRIN By similarity.

Subcellular location

Membrane › caveola By similarity. Cytoplasm › cytoskeleton By similarity. Golgi apparatus By similarity. Cell membrane By similarity. Note: Specifically associates with actin cytoskeleton in the G2 phase of the cell cycle, which is favored by interaction with NOSIP and results in a reduced enzymatic activity By similarity.

Tissue specificity

Expressed constitutively by vascular endothelium. Detected in alveolar and serosal epithelial cells as well as in endothelial cells in one day old rat. In adult lung, detected in rare endothelial cells.

Developmental stage

Detected at high levels in lung during the late fetal and postnatal period and at lower levels in adult.

Post-translational modification

Phosphorylation by AMPK at Ser-1176 in the presence of Ca2+-calmodulin (CaM) activates activity. In absence of Ca2+-calmodulin, AMPK also phosphorylates Thr-494, resulting in inhibition of activity.

Sequence similarities

Belongs to the NOS family.

Contains 1 FAD-binding FR-type domain.

Contains 1 flavodoxin-like domain.
