Recombinant human CSPG3 (Chondroitin Sulfate Proteoglycan 3), also known as NG2. is a transmembrane glycoprotein encoded by the CSPG4 gene. Structurally, it consists of a large extracellular domain with chondroitin sulfate glycosaminoglycan chains, a transmembrane segment, and a short cytoplasmic tail. It is primarily expressed in the nervous system, particularly on oligodendrocyte progenitor cells (OPCs), and plays critical roles in cell proliferation, adhesion, and migration.
In normal physiology, CSPG3 regulates neural development by mediating OPC interactions with the extracellular matrix, influencing myelination and axonal growth. It also interacts with growth factor receptors, such as PDGFRα, to modulate signaling pathways. Pathologically, CSPG3 is overexpressed in various cancers, including melanoma and glioblastoma, where it promotes tumor progression, angiogenesis, and metastasis by enhancing cell survival and invasiveness. Its involvement in glial scar formation post-central nervous system (CNS) injury further links it to inhibitory microenvironments that hinder axon regeneration.
Recombinant CSPG3 protein, produced via mammalian or bacterial expression systems, is widely used to study its structural-functional relationships, receptor interactions, and therapeutic targeting. Research focuses on blocking CSPG3 activity with antibodies or inhibitors in cancer therapy, as well as modifying its role in CNS repair to improve neural regeneration. This protein serves as a vital tool for both understanding disease mechanisms and developing biologics for oncology and neurology.
