Funkcija

Članovi porodice Trefoil odlikuju se po tome što imaju najmanje jednu kopiju trefoilski motiv, domena od 40 aminokiselina koji sadrži tri konzervirana disulfida. To su stabilni sekretorni proteini eksprimirani u gastrointestinalno sluzokoži. Njihove funkcije nisu definirane, ali mogu zaštititi sluznicu od ozljeda, stabilizirati sloj sluzi i uticati na zacjeljivanje epitela. Ovaj gen, koji je eksprimiran u sluznici želuca, također je proučavan zbog njegove ekspresije u ljudskim tumorima. Sa dva druga srodna gena člana porodice trefiola nalaze se u klasteru na hromosomu 21.^[6]

Vezivanje glikana

Sva tri ljudska trefoilska faktora su lektini koji su u specifičnoj interakciji sa disaharidom GlcNAc-α-1,4-Gal.^[8] Ovaj disaharid je neobičan glikotop za koji se zna da postoji samo na velikim, jako glikozilovanim, mucinima u sluznici. Unakrsnim povezivanjem mucina putem dvovalentno vezivanje ovog glikotopa, trefiolni faktori su tada u stanju da reverzibilno moduliraju debljinu i viskoznost sluzi.^[8]

Kod karcinoma želuca

Ekspresija TFF1 se često gubi u karcinomu želuca, vjerovatno preko mehanizma metilacija DNK, te se stoga smatra genom za supresiju tumora.^[9]
