Solute carrier family 17 (anion/sugar transporter), member 5, also known as SLC17A5 or sialin, is a protein which in humans is encoded by the SLC17A5 gene. This gene encodes a membrane transporter that exports free sialic acids that have been cleaved off of cell surface lipids and proteins from lysosomes. Mutations in this gene cause sialic acid storage diseases, including infantile sialic acid storage disorder and and Salla disease, an adult form. (provided by RefSeq)
Function: Primary solute translocator for anionic substances; particularly it is a free sialic acid transporter in the lysosomes (Probable)
