Versican is a large multi-domain chondroitin sulfate proteoglycan.
It is secreted by fibroblasts and other types of cells.
It has a N-terminal hyaluronic acid (HA) binding domain.
This domain has homology with the G1 and G2 domains of aggrecan, (G1 is the hyaluronic acid binding region), to cartilage link protein which stabilizes the binding of aggrecan to hyaluronic acid, and, to the hyaluronate receptor CD44.
In addition, versican also has a lectin like domain, a C-terminal compliment repeat, and two EGF-like repeats, all of which can be found in aggrecan.
Versican has an apparent molecular mass of ~1000kD, of which the core contributes 400kD from the 2409 amino acids, and the 12-15 covalently attached chondroitin sulfate chains make up the rest.
Applications:Suitable for use in ELISA, Immunohistochemistry, Western Blot and Immunoprecipitation.
