Elastin
Elastin — A highly elastic structural protein found in connective tissue, composed of short peptide sequences rich in glycine, valine, alanine, and proline.
What Is Elastin?
Elastin is a highly cross-linked, insoluble protein that provides elasticity and resilience to tissues (skin, lungs, arteries, ligaments). Elastin-like peptides (ELPs), based on the VPGXG repeat motif, exhibit temperature-responsive phase transition behavior and are used as purification tags, drug delivery vehicles, and tissue engineering scaffolds.
Peptide Applications
- ELPs: Soluble below transition temperature (Tt), aggregate above it. Tunable by guest residue (X) and chain length
- Drug delivery: ELP-peptide drug fusions form depots at body temperature for sustained release
- Skin peptides: Elastin-derived tripeptides (GHK, GVG) in cosmeceutical anti-aging formulations
