Targeting lysine acetylation readers and writers

Area of Science:

• Epigenetics and Molecular Biology
• Chemical Biology and Drug Discovery

Background:

• Lysine acetylation is a critical post-translational modification regulating protein function.
• Lysine acetyltransferases (KATs) and bromodomains (BrDs) are key regulators of gene expression, chromatin structure, and epigenetics.
• Dysregulation of KATs and BrDs is implicated in various diseases, notably cancer.

Purpose of the Study:

• To review the families, functions, and structures of KATs and BrDs.
• To highlight advancements in developing small molecule inhibitors targeting KATs and BrDs.
• To discuss the therapeutic potential of these targeted agents for disease treatment.

Main Methods:

• Literature review and synthesis of existing research on KATs and BrDs.
• Analysis of structural and functional data for KAT and BrD families.
• Summary of progress in medicinal chemistry and drug development for KAT/BrD inhibitors.

Main Results:

• Comprehensive overview of diverse KAT and BrD families and their biological roles.
• Identification of key structural features enabling targeted inhibition.
• Highlighting of promising small molecule agents, some in clinical trials, for KAT and BrD modulation.

Conclusions:

• KATs and BrDs are vital epigenetic regulators with significant therapeutic potential.
• Targeted small molecules offer a promising avenue for developing novel treatments for diseases driven by KAT/BrD dysregulation.
• Continued research in this area is crucial for advancing epigenetic therapies.
