Trr (Trithorax-related)

Trr (Trithorax-related) is a gene involved in regulating gene activity in cells by modifying how DNA is packaged. It helps keep certain genes active during development and cell differentiation by adding chemical marks to histones, the proteins around which DNA winds. This process ensures that genes essential for growth and development are turned on when needed. Trr is part of the broader Trithorax group, which counteracts gene-silencing mechanisms, maintaining a balance that allows proper gene expression. In summary, Trr plays a vital role in controlling gene activity to support normal development and cellular functions.
