Predicted to enable phosphomannomutase activity. Predicted to be involved in mannose metabolic process and protein N-linked glycosylation. Predicted to be located in cytoplasm; neuronal cell body; and nucleoplasm. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation and congenital disorder of glycosylation Ia. Orthologous to human PMM2 (phosphomannomutase 2).
