Lysine acetylation, a key epigenetic mark, is recognized by bromodomains. Small molecules targeting this interaction offer new ways to control gene expression for diseases like cancer.
Area of Science:
- Biochemistry and Molecular Biology
- Epigenetics and Gene Regulation
Background:
- Lysine acetylation is a critical post-translational modification regulating gene transcription.
- Bromodomains are protein modules that specifically recognize acetyl-lysine residues on histones and non-histone proteins.
Purpose of the Study:
- To explore the structural basis of bromodomain-acetyl-lysine recognition.
- To highlight the therapeutic potential of targeting bromodomain-acetyl-lysine interactions.
Main Methods:
- Structural analyses of bromodomain-acetyl-lysine peptide complexes.
- Review of small-molecule inhibitors targeting bromodomain proteins.
Main Results:
- Detailed insights into the selectivity and common features of bromodomain binding.
- Demonstration of bromodomain/acetyl-lysine interactions as key regulators in chromatin biology.
Conclusions:
- Modulating bromodomain-acetyl-lysine interactions with small molecules presents therapeutic opportunities for cancer and inflammatory diseases.
- This highlights the importance of understanding these interactions for controlling gene expression.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
