General description
The protein called Lubricin/Proteoglycan 4 is an important secreted protein in the joint critical for joint function and thus is also a focus of research in joint diseases as well. Lubricin/Proteoglycan 4 plays a role in boundary lubrication and prevents the deposition of cartilage from the synovial fluid by controlling the synovial growth of the synovial cells and inhibiting the adhesion of the cells to the cartilage surface. During development, Lubricin/Proteoglycan 4 also acts as a growth factor for hematopoietic and endothelial cell lineages, and Lubricin/Proteoglycan 4 appears important for proper barrier and lubrication development in tissues like the eye. Lubricin/Proteoglycan 4 is highly expressed in joints and near joint boundaries but can also be found in the brain, heart, lung, kidney and other tissues. Lubricin/Proteoglycan 4 has several isoforms that differ in their cell and tissue expression. Isoform C and D are the most widely expressed forms. Finally because of its effects on surfaces, Lubricin/Proteoglycan 4 is being examined in tissue engineering and artificial cartilage development as a treatment for joint diseases.
