Background: NG2/MCSP

NG2, also known as CSPG4, MCSP, and AN2, is a 400-500 kDa transmembrane chondroitin sulfate proteoglycan (CSPG) with a protein core of approximately 300 kDa. The extracellular region can be proteolytically shed from the cell surface (1-3). Mature human NG2 consists of a 2195 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 77 aa cytoplasmic domain (4). Within aa 1583-2224, human NG2/CSPG4 shares 83% aa sequence identity with mouse and rat CSPG4. NG2 binds to the extracellular matrix proteins Laminin, Tenascin, and Collagens II, V, and VI as well as to the growth factors FGF-2 and PDGF-AA (1, 5, 6). NG2 is expressed on glial cell progenitors known as O2A cells or NG2 glia (2, 7, 8). These cells are neuronally responsive and differentiate primarily into oligodendrocytes but also into astrocytes (8-10). NG2 associates with PDGF R alpha and the AMPA R subunit GluR2 (2, 7). It is up-regulated on microglial cells during inflammation and contributes to the induction of inflammatory mediators (11). Various CSPGs in the brain inhibit neurite outgrowth through interactions with Nogo Receptor/NgR1 and NgR3 (12). This recombinant protein product corresponds to the last 5 CSPG repeats, a region which can independently inhibit neurite outgrowth (13). NG2 is also expressed on vascular mural cells and capillaries (10, 14). It promotes vascular endothelial cell (EC) migration and angiogenesis through interactions with Galectin-3 and Integrin alpha 3 beta 1 on EC, Plasminogen, and Angiostatin (15, 16). NG2 is also expressed on a variety of tumors where it contributes to tumor cell adhesion, motility, and invasion (17).
