Struktura[uredi | uredi izvor]

Ovaj gen kodira člana porodice proteina F-kutije koju karakterizira približno 40 aminokiselinskih F-kutijskih motiva. Proteini F-kutije čine jednu od četiri podjedinice kompleksa ubikvitin protein-ligaze pod nazivom SCF-i (SKP1-kulin-F-kutija), koji sveprisutno funkcioniraju ovisno o fosforilaciji. Proteini F-boks-a podijeljeni su u tri klase: Fbws koji sadrže WD-40 domene, Fbls koji sadrže ponavljanje bogato leucinom i Fbx koji sadrže ili različite module interakcije protein-protein ili bez prepoznatljivih motiva. Protein kodiran ovim genom pripada klasi Fbls i, osim F-kutije, sadrži najmanje devet tandemskih ponavljanja bogatih leucinom.^[5]

Klinički značaj[uredi | uredi izvor]

Mutacije u ovom genu uzrokuju mitohondrijsku encefalomiopatiju s ranim početkom.^[7]^[8]
