Protein
Alpha-2,8-sialyltransferase 8F
Gene
St8sia6, Siat8f
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Prefers O-glycans to N-glycans or glycolipids as acceptor substrates. The minimal acceptor substrate is the NeuAc-alpha-2,36-Gal sequence at the non-reducing end of their carbohydrate groups.
