Both of these fucosyltransferases have been localized to the endoplasmic reticulum, which is unusual for glycosyltransferases, most of which function in the Golgi apparatus.
Ove fukoziltransferaze su izražene u endoplazmičnom retikulumu, što je je neobično za glikoziltransferaze, većina kojih deluje u Golđijevom aparatu.
