Enables calcium ion transmembrane transporter activity. Involved in calcium ion import. Acts upstream of or within negative regulation of melanin biosynthetic process. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Predicted to be active in trans-Golgi network. Is expressed in several structures, including brain; ear; gonad; spleen; and submandibular gland. Used to study ocular albinism. Human ortholog(s) of this gene implicated in oculocutaneous albinism type VI. Orthologous to human SLC24A5 (solute carrier family 24 member 5). [provided by Alliance of Genome Resources, Apr 2022]
