Predicted to enable calcium ion transmembrane transporter activity and manganese ion transmembrane transporter activity. Predicted to be involved in cellular cation homeostasis; metal ion transport; and protein N-linked glycosylation. Predicted to be located in endosome membrane; lysosomal membrane; and trans-Golgi network membrane. Predicted to be active in Golgi apparatus. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type IIk. Orthologous to human TMEM165 (transmembrane protein 165).
