General annotation (Comments)

Function	Catalyzes the reaction that attaches fucose through an O-glycosidic linkage to a conserved serine or threonine residue in EGF domains. Plays a crucial role in Notch signaling. Ref.1 Ref.6
Catalytic activity	Transfers an alpha-L-fucosyl residue from GDP-beta-L-fucose to the serine hydroxy group of a protein acceptor.
Cofactor	Manganese. Ref.6
Pathway	Protein modification; protein glycosylation.
Subcellular location	Endoplasmic reticulum By similarity.
Tissue specificity	Highly expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Ref.1
Sequence similarities	Belongs to the glycosyltransferase 68 family.
