VCAN

A gene on chromosome 5q14.3 that encodes an aggrecan/versican proteoglycan, which is a large chondroitin sulphate and major component of the extracellular matrix involved in cell adhesion, proliferation, migration and angiogenesis, and which plays a central role in tissue morphogenesis and maintenance.

Molecular pathology
VCAN mutations cause Wagner syndrome type 1.

The aggrecanase and proteoglycanase clades (ADAMTS1, 4, 5, 8, 9, 15, and 20) can cleave hyaluronan-binding chondroitin sulfate proteoglycans, a type of extracellular proteins, including aggrecan, versican, brevican, and neurocan [2].
The ECM structural substrates, such as versican, aggrecan, and collagen are degraded by the ADAMTS family members (14).

MMPs are active at neutral pH and can therefore catalyze the normal turnover of extracellular matrix (ECM) macromolecules such as interstitial and basement membrane collagens, proteoglycans such as aggrecan, decorin, biglycan, fibromodulin, and versican, as well as accessory ECM proteins such as fibronectin.
A study showed that another long-chain glycosaminoglycan-hyaluronan could interact with versican to create matrices, which are required for arterial smooth muscle growth during the vascular disease [45].
Expression of versican, Cd133, SCF (stem cell factor), ET-1 (endothelin-1), and bFGF (fibroblast growth factor) was observed during the process of differentiation [90].
Specific proteins, such as asporin and tenomodulin, were limited to tendons, while versican, proteoglycan 4, and SOD3 were ligament-specific (Figure 1).
Chondroitin sulfate proteoglycans (CSPGs), including the lecticans aggrecan, versican, neurocan, and brevican, are joined to the hyaluronic acid polymer through "link" proteins including cartilage link protein (Crtl1).
Glioma-derived versican interacts with TLR2, inducing CNS microglia and macrophages to express membrane type 1-matrix metalloproteinase 1 (MT1-MMP) that activates MMP2 [99].
