Predicted to enable hyaluronan synthase activity and identical protein binding activity. Predicted to be involved in several processes, including extracellular polysaccharide biosynthetic process; hyaluronan biosynthetic process; and positive regulation of hyaluranon cable assembly. Predicted to be located in cytoplasm; hyaluranon cable; and nucleus. Predicted to be integral component of plasma membrane. Biomarker of pulmonary hypertension. Orthologous to human HAS3 (hyaluronan synthase 3). [provided by Alliance of Genome Resources, Apr 2022]
