Sialidase-2 is an enzyme that in humans is encoded by the NEU2 gene. ^{[5] [6] [7]}

This gene belongs to a family of glycohydrolytic enzymes which remove sialic acid residues from glycoproteins and glycolipids. Expression studies in COS-7 cells confirmed that this gene encodes a functional sialidase. Its cytosolic localization was demonstrated by cell fractionation experiments. ^[7]
