CHST13A gene on chromosome 3q21.3 that encodes a sulfotransferase which catalyses the transfer of sulfate to position 4 of the GalNAc residue of chondroitin, generating chondroitin sulfate, the predominant proteoglycan present in cartilage and on the surfaces of many cells and in the extracellular matrix.
