Funkcija

uredi

Protein koji je kodiran ovim genom sličan je po sekvenci i možda funkciji produktu retinoblastomskog 1 (RB1) gena. RB1 genski proizvod je protein za supresiju tumora koji se je uključen u regulaciju ćelijskog ciklusa, budući da je fosforiliran u S u M faznoj tranziciji i defosforiliran u G1 fazi ćelijskog ciklusa. I protein RB1 i proizvod ovog gena mogu formirati kompleks sa adenovirusnim E1A proteinom i SV40 veliki T-antigen, sa SV40 velikim T-antigenom, vezujući se samo za nefosforilirani oblik svakog proteina. Osim toga, oba proteina mogu inhibirati transkripciju gena ćelijskog ciklusa koji sadrže E2F mjesta vezanja u svojim promotorima. Zbog sekvencne i biohemijskih sličnosti sa RB1 proteinom, smatra se da protein kodiran ovim genom takođe može biti supresor tumora. Za ovaj gen, pronađene su dvije varijante transkripta koje kodiraju različite izoforme.[5]
