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. Ref.3 UniProtKB Q9H488

Catalytic activity

Transfers an alpha-L-fucosyl residue from GDP-beta-L-fucose to the serine hydroxy group of a protein acceptor. Ref.3

Pathway

Protein modification; protein glycosylation.

Subunit structure

Monomer. Ref.3

Subcellular location

Endoplasmic reticulum By similarity.

Miscellaneous

Manganese is bound to the substrate GDP-fucose, but is not required for enzyme activity.

Sequence similarities

Belongs to the glycosyltransferase 68 family.
