LipA-Human Elastin (EP20-24-24) Fusion Protein


Elastin is a polymeric extracellular matrix protein found in tissues that require the ability to extend and recoil. Examples of elastin containing tissues include arteries, lungs, ligaments and skin. Construct EP20-24-24 for human elastin polypeptide consists of distinct exons which code for alternating hydrophobic regions and crosslinking domains from the human elastin polypeptide gene 1.

Under appropriate conditions of temperature and ionic strength, elastin polypeptide undergoes a self-aggregation process known as coacervation. Coacervation is usually induced by an increase in temperature and causes the protein to separate from the solution as a second phase. Unlike most proteins which undergo denaturation when the temperature of the solution increases, elastin polypeptides become more ordered through coacervation 2.


LipA is a signal peptide from the B. subtilis genome. In general, signal peptides are responsible for directing preproteins (secretory proteins with a signal peptide region attached)through an appropriate secretory pathway3. LipA has been successfully used in the secretion of heterologous proteins such as cutinase by B. subtilis.
