Synergistic role of E1A-Binding proteins and tissue-specific transcription factors in differentiation

In this review, the complex relationship between tissue-specific transcription factors and genes regulating cell cycle is taken into account. Both E1-A binding proteins belonging to the family of the retinoblastoma gene product and the CBP/p300 coactivator of transcription interact physically and functionally with tissue-specific transcription factor. The relationship between these two classes of molecules regulates cell fate in differentiating cells, deciding whether cells continue to replicate, undergo apoptosis or terminally differentiate. We provide here an update on the recent advances in this field and some models of interaction between E1A binding protein and tissue-specific transcription factors.
