Nitric oxide (NO) is a potent mediator in biologic processes such as neurotransmission, inflammatory response, and vascular homeostasis. NOSTRIN binds the enzyme responsible for NO production, endothelial NO synthase (ENOS; MIM 163729), and triggers the translocation of ENOS from the plasma membrane to vesicle-like subcellular structures, thereby attenuating ENOS-dependent NO production.[supplied by OMIM, Apr 2004],

Function:
Domain:The FCH domain is necessary for membrane targeting.,Domain:The SH3 domain mediates interaction with NOS3, DNM2 and WASL.,Function:Multivalent adapter protein which may decrease NOS3 activity by inducing its translocation away from the plasma membrane.,similarity:Contains 1 FCH domain.,similarity:Contains 1 SH3 domain.,subcellular location:Enriched in selected actin structures.,subunit:Homotrimer. Interacts with DAB2 (By similarity). Interacts with NOS3, DNM2, WASL and CAV1.,tissue specificity:Expressed at highest levels in heart, kidney, placenta and lung, and at lowest levels in brain, thymus and spleen. Present in vascular endothelial cells and placenta. Over-expressed in placenta from women with pre-eclampsia (at protein level).,
