Predicted to enable zinc ion transmembrane transporter activity. Predicted to be involved in cellular zinc ion homeostasis and zinc ion import across plasma membrane. Predicted to act upstream of or within cellular response to zinc ion starvation and zinc ion transport. Predicted to be located in apical plasma membrane and endosome. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in acrodermatitis enteropathica. Orthologous to human SLC39A4 (solute carrier family 39 member 4).
