We also demonstrate that a p110RB1 mutant , which is refractory to cell cycle phosphorylation but intact in E1a / large T antigen - binding properties , represses EIIaE with 50 - to 80 - fold greater efficiency than wild - type p110RB1 .
 GENE: p110RB1 mutant; GENE: E1a; GENE: large T antigen; GENE: EIIaE; GENE: wild - type p110RB1
