The extracellular region can be proteolytically shed from the cell surface. Mature human NG2 consists of a 2195 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 77 aa cytoplasmic domain. 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. NG2 is expressed on glial cell progenitors known as O2A cells or NG2 glia. These cells are neuronally responsive and differentiate primarily into oligodendrocytes but also into astrocytes. NG2 associates with PDGF R alpha and the AMPA R subunit GluR2. It is up-regulated on microglial cells during inflammation and contributes to the induction of inflammatory mediators. Various CSPGs in the brain inhibit neurite outgrowth through interactions with Nogo Receptor/NgR1 and NgR3. This recombinant protein product corresponds to the last 5 CSPG repeats, a region which can independently inhibit neurite outgrowth. NG2 is also expressed on vascular mural cells and capillaries. 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. NG2 is also expressed on a variety of tumors where it contributes to tumor cell adhesion, motility, and invasion...

It is a pleiotropic molecule that plays a central role in inflammation, immune system development, apoptosis, and lipid metabolism. Rat TNF-alpha consisitsBackground:Tumor necrosis factor alpha (TNF-alpha ), also known as cachectin and TNFSF2, is the prototypic ligand of the TNF superfamily. It is a pleiotropic molecule that plays a central role in inflammation, immune system development, apoptosis, and lipid metabolism. Rat TNF-alpha consisits of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 179 aa extracellular domain (ECD). Within the ECD, rat TNF-alpha shares 94% aa sequence identity with mouse and 69%-76% with bovine, canine, cotton rat, equine, feline, human, porcine, and rhesus TNF-alpha. TNF-alpha is produced by a wide variety of immune, epithelial, endothelial, and tumor cells. TNF-alpha is assembled intracellularly to form a noncovalently linked homotrimer which is expressed on the cell surface. Cell surface TNF-alpha can induce the lysis of neighboring tumor cells and virus infected cells, and it can generate its own downstream cell signaling following ligation by soluble TNFR I. Shedding of membrane bound TNF-alpha by TACE/ADAM17 releases the bioactive cytokine, a 55 kDa soluble trimer of the TNF-alpha extracellular domain. TNF-alpha binds the ubiquitous 55-60 kDa TNF RI and the hematopoietic cell-restricted 80 kDa TNF RII, both of which are also expressed as homotrimers. Both type I and type II receptors bind TNF-alpha with comparable affinity, although only TNF RI contains a cytoplasmic death domain which triggers the activation of apoptosis. Soluble forms of both types of receptors are released and can neutralize the biological activity of TNF-alpha. Post-translational modificationsThe soluble form derives from the membrane form by proteolytic processing.The membrane form, but not the soluble form, is phosphorylated on serine residues.Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1.O-glycosylated; glycans contain galactose, N-acetylgalactosamine and N-acetylneuraminic acid...
