Predicted to enable zinc ion transmembrane transporter activity. Predicted to be involved in regulation of sequestering of zinc ion; response to zinc ion; and zinc ion import into synaptic vesicle. Predicted to act upstream of or within positive regulation of transport. Predicted to be located in hippocampal mossy fiber; late endosome; and synaptic vesicle membrane. Predicted to be active in glutamatergic synapse; hippocampal mossy fiber to CA3 synapse; and plasma membrane. Predicted to be integral component of synaptic vesicle membrane. Orthologous to human SLC30A3 (solute carrier family 30 member 3). [provided by Alliance of Genome Resources, Apr 2022]
