Epigenetics
Epigenetics — The study of heritable changes in gene expression that do not involve DNA sequence changes, with histone-modifying peptide signals being a central mechanism.
What Is Epigenetics?
Epigenetics studies heritable changes in gene expression that do not involve DNA sequence changes. Peptide-based epigenetic modulators target histone-modifying enzymes (HDACs, HATs, methyltransferases) or read epigenetic marks (bromodomain inhibitors). Histone tails are heavily modified peptide sequences whose PTM patterns control chromatin accessibility.
Peptide Connections
- Histone tail peptides: Synthetic peptides with specific acetylation/phosphorylation/methylation patterns as assay substrates
- HDAC inhibitors: Cyclic depsipeptide romidepsin (FK228) is an FDA-approved HDAC inhibitor
- GHK-Cu: Gene expression analysis shows epigenetic-level effects on tissue remodeling genes
