Enables calcium channel inhibitor activity. Involved in cellular divalent inorganic cation homeostasis; negative regulation of ion transport; and zinc ion transport. Acts upstream of or within in utero embryonic development. Predicted to be located in T-tubule; cytoplasm; and nuclear membrane. Predicted to be active in Golgi apparatus and endoplasmic reticulum. Predicted to be integral component of membrane. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and nose. Orthologous to human SLC30A1 (solute carrier family 30 member 1). [provided by Alliance of Genome Resources, Apr 2022]
