Protein Structure

UniProt Annotation

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. May play a significant role in normal and abnormal limb development. {ECO:0000269PubMed:9843834}.

Subcellular Localization

Membrane, caveola {ECO:0000250}. Cytoplasm, cytoskeleton {ECO:0000250}. Golgi apparatus {ECO:0000250}. Cell membrane {ECO:0000250}. 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. {ECO:0000250}.
