Predicted to enable hyaluronan synthase activity and hyalurononglucosaminidase activity. Involved in response to virus. Acts upstream of or within embryonic skeletal joint morphogenesis. Predicted to be located in extracellular space; hyaluranon cable; and lysosome. Predicted to be active in cytoplasmic vesicle. Is expressed in liver and metanephros. Used to study mucopolysaccharidosis IX. Human ortholog(s) of this gene implicated in mucopolysaccharidosis and mucopolysaccharidosis IX. Orthologous to human HYAL1 (hyaluronidase 1).
