Chondroitin sulfate (CS) is a glycosaminoglycan which is an important structural component of the extracellular matrix;and which links to proteins to form proteoglycans. Chondroitin sulfate E (CS-E) is an isomer of chondroitin sulfate in;which the C-4 and C-6 hydroxyl groups are sulfated. This gene encodes a type II transmembrane glycoprotein that acts;as a sulfotransferase to transfer sulfate to the C-6 hydroxal group of chondroitin sulfate. This gene has also been;identified as being co-expressed with RAG1 in B-cells and as potentially acting as a B-cell surface signaling;receptor. Alternative splicing results in multiple transcript variants encoding distinct isoforms.
