Elastin is a highly elastic protein found in connective tissue that allows tissues in the body to resume their shape after stretching or contracting. It is particularly important in skin, helping it to return to its original position when poked or pinched. Elastin is also found in load-bearing tissues where mechanical energy needs to be stored. It is encoded by the ELN gene and produces a protein that forms elastic fibers, containing hydrophobic regions bounded by lysine crosslinks.

3. Elastin is also an important load-bearing tissue
in the bodies of vertebrates and used in places
where mechanical energy is required to be
stored. In humans, elastin is encoded by
the ELN gene.

4. Function
The ELN gene encodes a protein that is one of
the two components of elastic fibers. The
encoded protein is rich in hydrophobic amino
acids such as glycine and proline, which form
mobile hydrophobic regions bounded by
crosslinks between lysine residues.
