Structure of the retinoblastoma protein pocket domain in complex with adenovirus E1A CR1 domain
Overview
The adenovirus (Ad) E1A (Ad-E1A) oncoprotein mediates cell transformation, in part, by displacing E2F transcription factors from the retinoblastoma, protein (pRb) tumor suppressor. In this study we determined the crystal, structure of the pRb pocket domain in complex with conserved region 1, (CR1) of Ad5-E1A. The structure and accompanying biochemical studies, reveal that E1A-CR1 binds at the interface of the A and B cyclin folds of, the pRb pocket domain, and that both E1A-CR1 and the E2F transactivation, domain use similar conserved nonpolar residues to engage overlapping sites, on pRb, implicating a novel molecular mechanism for pRb inactivation by a, viral oncoprotein.
