Proteins are used for all kinds of structure and function inside cells. Proteins make up structural molecules such as the cytoskeleton that allow cells to move, grow, divide and keep a specific structure to do their job in the body. Proteins also make up enzymes, that perform all the ...
The PcG and TrxG proteins are recruited to cis-regulatory elements called Polycomb/Trithorax response elements (PREs). The PcG and TrxG proteins act antagonistically through PREs to maintain silent and active gene expression states, respectively. These states are initiated by transcription factors that...
