Protein
Alpha-N-acetylneuraminide alpha-2,8-sialyltransferase
Gene
St8sia1, Siat8, Siat8a
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Involved in the production of gangliosides GD3 and GT3 from GM3; gangliosides are a subfamily of complex glycosphinglolipds that contain one or more residues of sialic acid.1 Publication
