Summaries for NEU2 Gene

Entrez Gene Summary for NEU2 Gene

  • 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for NEU2 Gene

NEU2 (Neuraminidase 2) is a Protein Coding gene. Diseases associated with NEU2 include Discrete Subaortic Stenosis and Subvalvular Aortic Stenosis.
