Predicted to enable phosphomannomutase activity. Predicted to be involved in mannose metabolic process and protein N-linked glycosylation. Located in cytoplasm and neuronal cell body. Is expressed in several structures, including alimentary system; brain; liver; nose; and respiratory system. Used to study congenital disorder of glycosylation type I. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation and congenital disorder of glycosylation Ia. Orthologous to human PMM2 (phosphomannomutase 2).
