Chondroitin sulfate proteoglycan

Chondroitin sulfate proteoglycans (CSPGs) are proteoglycans consisting of a core protein and chondroitin sulfate. They are structural components of a variety of human tissues, for example of cartilage.

The following CSPGs have been identified:
 * CSPG1 (aggrecan)
 * CSPG2 (versican). Versican has chains of dermatan sulfate in addition to chondroitin sulfate.
 * CSPG3 (neurocan)
 * CSPG4 (melanoma-associated chondroitin sulfate proteoglycan)
 * CSPG5
 * CSPG6 (SMC3, structural maintenance of chromosomes 3)
 * CSPG7 (brevican)
 * CSPG8 (CD44, cluster of differentiation 44)
