Chondroitin sulfate proteoglycan 4, also known as melanoma-associated chondroitin sulfate proteoglycan (MCSP) or neuron-glial antigen 2 (NG2), is a chondroitin sulfate proteoglycan that in humans is encoded by the CSPG4gene.[1][2][3]
CSPG4 plays a role in stabilizing cell-substratum interactions during early events of melanoma cell spreading on endothelialbasement membranes. It represents an integral membrane chondroitin sulfate proteoglycan expressed by human malignant melanoma cells.[3]
