Specificity / Sensitivity
NG2/CSPG4 Antibody recognizes endogenous levels of total NG2/CSPG4 protein.
Species Reactivity: Human, Mouse, Rat
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp1410 of human NG2/CSPG4 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
The chondroitin sulfate proteoglycan NG2 is a type I membrane protein expressed by subpopulations of glia, including oligodendroglial precursor cells and a variety of tumor cells. Normal precursor cells and malignant tumor cells migrate and proliferate, but there is evidence that cells may not be able to engage in both activities at the same time. However, NG2 is involved in promoting both proliferation and motility (1). The extracellular domain of NG2 sequesters growth factors and binds to both growth factor receptors and extracellular matrix ligands such as fibronectin, collagens, and laminin. The cytoplasmic domain is involved in activating Rac, Cdc42, and p130 Cas (2). PKCα phosphorylates NG2 at Thr2256, triggering the redistribution of NG2 from apical microprocesses to lamellipodia, accompanied by enhanced cell motility (3). ERK phosphorylates NG2 at Thr2314, stimulating cell proliferation (4).
