Summaries for NEU3 Gene

Entrez Gene Summary for NEU3 Gene

  • This gene product belongs to a family of glycohydrolytic enzymes which remove sialic acid residues from glycoproteins and glycolipids. It is localized in the plasma membrane, and its activity is specific for gangliosides. It may play a role in modulating the ganglioside content of the lipid bilayer. [provided by RefSeq, Jul 2008]

GeneCards Summary for NEU3 Gene
