Trithorax-group proteins
Trithorax-group proteins (TrxG) are a heterogeneous collection of proteins whose main action is to maintain gene expression. They can be categorized into three general classes based on molecular function:
- histone-modifying TrxG proteins
- chromatin-remodeling TrxG proteins
- DNA-binding TrxG proteins,
plus other TrxG proteins not categorized in the first three classes.
