Description

Antigen: human eNOS amino acids 1186-1203 (RGAVPWAFDPPGSDTNSP) · Host: rabbit · Application(s): WB, IP; other applications not tested · eNOS catalyzes the formation of NO from L-arginine in many cell types including vascular endothelium, bronchiolar epithelium, cardiac myocytes, spleen, and kidney.1,2,3 Although eNOS was initially characterized as a constitutive enzyme, expression of eNOS mRNA is altered by many factors including shear stress, fibroblast growth factor, hypoxia, and LPS.4,5,6 eNOS is myristoylated and palmitoylated at the N-terminus, modifications which are required for localization to the plasmalalemmal caveolae of endothelial cells.7,8,9,10,11 Additionally, eNOS is phosphorylated on Ser1179 by protein kinase Akt resulting in an increase in NOS activity.12,13,14
