Funkcija[uredi | uredi izvor]

Ovaj gen kodira člana porodice proteina TGF-beta. Sličan izlučeni protein kod miša ima ulogu u određivanju asimetrije lijevo-desno u sistemima organa tokom razvoja. Alternativna prerada ovog proteina može dati tri različita izoformna proizvoda. Ovaj gen je usko povezan i sa srodnim članom porodice i sa srodnim pseudogenom.
