Versican is a large extracellular matrix protein that plays a crucial role in cell signaling and tissue organization. It is primarily found in connective tissues and is involved in various biological processes, including cell adhesion, migration, and proliferation. Versican is known for its ability to bind water, which helps maintain tissue hydration and elasticity. This protein is composed of multiple domains, allowing it to interact with other molecules, such as hyaluronic acid and growth factors. Versican is important in development, wound healing, and inflammation, and its dysregulation has been linked to several diseases, including cancer and osteoarthritis.
