Enables chondroitin 4-sulfotransferase activity. Involved in chondroitin sulfate biosynthetic process and positive regulation of response to oxidative stress. Predicted to be located in Golgi membrane.
Enables hexosaminidase activity. Involved in chondroitin sulfate catabolic process. Expressed in PLML; PLMR; head; intestinal cell; and vulva. Human ortholog(s) of this gene implicated in mucopolysaccharidosis IX. Is an ortholog of human HYAL2 (hyaluronidase 2).
