General description

Nerve/glial antigen 2 (NG2), a high molecular mass melanoma- associated antigen (HMW-MAA), is a large integral membrane, cell surface type I transmembrane protein that is covalently modified with chondroitin sulfate glycosaminoglycan.

Immunogen

a recombinant extracellular portion of human NG2 proteoglycan

Application

Monoclonal Anti-NG2/CSPG4 antibody produced in mouse used in flow cytometry and immunocytochemistry.

Biochem/physiol Actions

Nerve/glial antigen 2 (NG2) plays a central role in linking multiple oncogenic pathways required for malignant progression. NG2 expression in radial growth phase (RGP) human melanomas enables migration, protease activation and epithelial to mesenchymal transition, which is important in primary tumors for facilitating progression from a radial to vertical growth phase phenotype. It regulates sustained, high-level activation of key survival and growth pathways, integrin-regulated focal adhesion kinase (FAK), extracellular signal-regulated kinases 1 and 2 (ERK 1,2) and phosphoinositide 3-kinase (PI3K)/AKT pathways.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Proteoglycans are ubiquitous dynamic molecules that are made up of a protein core to which specific linear glycosylation structures, known as glycosaminoglycans, have been covalently coupled. They have roles in many biological and pathological processes, which have been shown to
