Predicted to enable mannose-6-phosphate isomerase activity. Predicted to be involved in GDP-mannose biosynthetic process; cell wall mannoprotein biosynthetic process; and protein glycosylation. Predicted to act upstream of or within mannose to fructose-6-phosphate metabolic process. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in carbohydrate metabolic disorder and congenital disorder of glycosylation Ib. Orthologous to human MPI (mannose phosphate isomerase).
