Podjedinica proteina 1 T-kompleksa beta je protein koji je kod ljudi kodiran iz gena CCT2.^[5]^[6]

Funkcija uredi

Ovaj gen kodira molekulski šaperon koji je član kompleksa TRiC. Ovaj kompleks sastoji se od dva identična naslagana prstena, od kojih svaki sadrži po osam različitih proteina. Nerazvijeni polipeptidi ulaze u središnju šupljinu kompleksa i savijaju se na način koji je ovisan o ATP-u. Kompleks savija različite proteine, uključujući aktin i tubulin. Primijećene su alternativne transkripcijske spojne varijante gena, opisane u ovom transkriptu, ali nisu detaljno okarakterizirane.

Interakcije uredi

Pokazano je da CCT2 (gen) ima interakcije s PPP4C.^[7]^[8]
