[Polycomb and trithorax control genome expression by determining the alternative epigenetic states of chromatin for
Abstract:
The Polycomb (PcG) and Trithorax (TrxG) group proteins are essential for development in all multicellular organisms. Mutations of the PcG and TrxG genes act as early embryonic lethals, while their overexpression correlates with malignancies. Comparative genome analysis showed that PcG and TrxG form a binary regulatory system that functions as an epigenetic rheostat to determine the threshold levels of extracellular signals affecting the expression levels of key developmental genes.

Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
