Phospho-iNOS (Tyr-1055) synthetic peptide (coupled to carrier protein) corresponds to amino acids surrounding Tyr-1055 in human iNOS. This sequence is well conserved in rat and mouse iNOS, and has some homology to the conserved sites in eNOS (Tyr-1087) and nNOS (Tyr-1326).

Product Specific Information

The antibody detects a 130 kDa* protein corresponding to induced NOS on SDS-PAGE immunoblots of mouse macrophages treated with LPS followed by pervanadate. The antibody also detects a 150 kDa doublet that corresponds with higher molecular weight forms of NOS, which are also observed using other anti-iNOS antibodies. In addition, the antibody detects a non-specific 120 kDa band that has not been identified.

Target Information

iNOS (Inducible Nitric oxide, NO, NOS) is an inorganic, gaseous free radical that carries a variety of messages between cells. Vasorelaxation, neurotransmission and cytotoxicity can all be potentiated through cellular response to NO. NO production is mediated by members of the nitric oxide synthase (NOS) family. iNOS is expressed in liver and inducible by a combination of lipopolysaccharide and certain cytokines. NOS catalyzes the oxidization of L-arginine to produce L-citrulline and NO. Two constitutive isoforms, brain or neuronal NOS (b or nNOS, type I) and endothelial cell NOS (eNOS, type III), and one inducible isoform (iNOS, type II), have been cloned. All NOS isoforms contain calmodulin, nicotinamide adenine dinucleotide phosphate (NADPH), flavin adenine dinucleotide (FAD), and flavin mononucleotide (FMN) binding domains. iNOS is found in a variety of cell types including macrophages, hepatocytes, synoviocytes, and smooth muscle cells. Cytokines such as interferon-gamma (IFN), tumor necrosis factor (TNF), interleukin-1 and -2, and lipopolysaccarides (LPS) cause an increase in iNOS mRNA, protein, and activity levels. Protein kinase C-stimulating agents exhibit the same effect on iNOS activity. After cytokine induction, iNOS exhibits a delayed activity response which is then followed by a significant increase in NO production over a long period of time. Three related iNOS pseudogenes are located within the Smith-Magenis syndrome region on chromosome 17. Diseases associated with iNOS dysfunction include achalasia and impotence.
