Immunogen Phosphorylated Human eNOS (pS633) Peptide
Clone DH1
Isotype IgG1
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name eNOS
Background Nitirc oxide synthase (NOS), a cell type specific enzyme, catalyzes the synthesis of nitric oxide (NO). NO is a short-lived radical that transmits signals involved in vasorelaxation, neurotransmission, and cytoxicity. In neurons and endothelial cells, constitutive NOS (cNOS) is activated by agonists that increase intracellular Ca2+ levels and enhance calmodulin binding. Neuronal NOS (nNOS) and endothelial NOS (eNOS) have recognition sites for NADPH, FAD, FMN, and calmodulin. eNOS has a unique N-myristylation consensus sequence that may explain its membrane localization. Various protein kinases have been implicated in regulation of eNOS activity, including AMPK, PKA, PKB/Akt, PKC, and CaM Kinase II. During VEGF stimulation, eNOS is transiently phosphorylated at Ser-1177 by PKB/Akt and dephosphorylated at Thr-495. At later time points, VEGF stimulation leads to an increase in Thr-495 phosphorylation mediated by PKC and a decrease in Ser-1177 phosphorylation. In addition, Ser-633 amd Ser-1177 are phosphorylated by PKA and PKG in vitro. Thus, eNOS activity may be regulated through complex phosphorylation events mediated by multiple kinases at various phosphorylation sites.

anti-Nitric Oxide Synthase 3 (Endothelial Cell) (NOS3) (pSer633) antibody Western blot analysis for eNOS (pS633). Human endothelial cells were either left untreated (lane 1) or were treated with 200 U/mL of lambda phosphatase for 1 hour at 37°C (lane 2). The top panel was probed with a mouse anti-eNOS antibody (ABIN967886) and the bottom panel was probed with the mouse anti-eNOS (pS633) antibody at a 1:500 dilution with a band observable at ~ 140 kDa.
