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 CSPG4 gene.^[5][6][7]

Function

CSPG4 plays a role in stabilizing cell-substratum interactions during early events of melanoma cell spreading on endothelial basement membranes. It represents an integral membrane chondroitin sulfate proteoglycan expressed by human malignant melanoma cells.^[7]

Implications in disease

CSPG4/NG2 is also a hallmark protein of oligodendrocyte progenitor cells (OPCs)^[8] and OPC dysfunction has been implicated as a candidate pathophysiological mechanism of familial schizophrenia.^[9] A research group investigating the role of genetics in schizophrenia, reported, two rare missense mutations in CSPG4 gene, segregating within families (CSPG4^A131T and CSPG4^V901G mutations). The researchers also demonstrate that the induced pluripotent stem cells (iPSCs)-derived OPCs from CSPG4^A131T mutation carriers exhibited abnormal post-translational processing, subcellular localization of the mutant NG2 protein, aberrant cellular morphology, and a decreased cell viability and myelination potential. In vivo diffusion tensor imaging of the brain of CSPG4^A131T mutation carriers demonstrated a reduced white matter integrity compared to the unaffected sibling and matched general population controls.^[10]
