Predicted to enable sialic acid transmembrane transporter activity. Acts upstream of or within response to bacterium. Located in cytoplasmic vesicle and plasma membrane. Is expressed in several structures, including gut; liver; metanephros; nervous system; and sensory organ epithelium. Used to study lysosomal storage disease and sialuria. Human ortholog(s) of this gene implicated in sialuria. Orthologous to human SLC17A5 (solute carrier family 17 member 5). [provided by Alliance of Genome Resources, Apr 2022]
