Sialidase-2 is an enzyme that in humans is encoded by the NEU2 gene.^[3][4][5]

This gene belongs to a family of glycohydrolytic enzymes which remove sialic acid residues from glycoproteins and glycolipids. Expression studies in COS7 cells confirmed that this gene encodes a functional sialidase. Its cytosolic localization was demonstrated by cell fractionation experiments.^[5]
