Predicted to enable calcium ion binding activity; heparosan-N-sulfate-glucuronate 5-epimerase activity; and protein homodimerization activity. Predicted to be involved in heparan sulfate proteoglycan biosynthetic process and heparin biosynthetic process. Predicted to be active in Golgi apparatus. Orthologous to human GLCE (glucuronic acid epimerase). [provided by Alliance of Genome Resources, Apr 2022]
