What Is Elastin?
Elastin is a protein in the fiber of the connective tissue of the skin that provides a resilient and elastic quality. It's what gives skin that bouncy, full look and feel so often associated with a youthful, healthy complexion. Elastin depletes naturally with age, leaving skin more prone to visible sagginess, fine lines and wrinkling.
What Causes a Loss of Skin Elastin?
Many factors affect how skin ages. For the most part, the breakdown of collagen and loss of elasticity is perfectly normal — as you age, you may notice your skin becomes more dry, dull and lined, and that's natural. However, these changes may also stem from:
How to Improve Skin Appearance
Thankfully, there are ways to address the changes caused by elastin-depletion in your skin— and it's not just endless green juice and early nights.
What Is Elastin?
What is elastin? Elastin is a protein and major constituent of elastic fibers, which make up elastic connective tissue. Generally speaking, connective tissue supports, protects and provides structure to other tissues and organs in the body.
Elastin Structure
As discussed, elastin is a protein, and proteins are made up of a sequence of amino acids. The elastin structure consists of the amino acids:
What is the ELN gene?
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.
Why does trophoelastin aggregate?
Tropoelastin aggregates at physiological temperature due to interactions between hydrophobic domains in a process called coacervation. This process is reversible and thermodynamically controlled and does not require protein cleavage. The coacervate is made insoluble by irreversible crosslinking.
What enzyme is responsible for crosslinking elastin?
The enzyme that performs the crosslinking is lysyl oxidase, using an in vivo Chichibabin pyridine synthesis reaction.
What is the role of elastin in the lungs?
Elastin is also very important in the lungs, elastic ligaments, elastic cartilage, the skin, and the bladder.

What happens if you lose elastin?
The lungs may overinflate, making them vulnerable to further damage.
Why do lungs need elastin?
Elastin provides pressure on the balloons to prevent hyperinflation and maintain proper lung function . If the elastin is damaged, such as occurs due to inflammation caused by inhaled irritants in the case of emphysema, pressure in the alveoli is lost and airflow is reduced. The lungs may overinflate, making them vulnerable to further damage.
What happens when you are stressed?
When you are stressed out, your body releases stress hormones like cortisol, and we know that cortisol breaks down the collagen and elastin fibers in the skin. The higher your stress level, the more cortisol is produced, and the more skin fibers are damaged.
What is collagen and elastin?
You’ve probably heard these two words and over again when it comes to skincare. They’re what your skin needs to delay the appearance of aging, they say, and you nod your head and agree.
Why is it important to use moisturizer?

Does UV light damage collagen?
As noted above, UV rays from the sun can damage both collagen and elastin fibers, and once they are damaged, elastin fibers, in particular, are usually very difficult to repair. Indeed, some studies have found that long-term UV radiation leads not only to wrinkle formation but decreases in skin elasticity and the curling of elastin fibers in the skin.
What happens to elastin fibers in the sun?
As elastin fibers degenerate, the skin starts to sag and stretch out, and it eventually becomes unable to bounce back.
Why does elastin biosynthesis slow down?
Extrinsic aging is often the result of poor lifestyle habits and environmental damage. Not only does elastin biosynthesis slow down as you age, existing elastic fibers in your skin also start to degenerate and damage accumulates in existing elastin. This means that your skin loses its ability to rebound.
How to reduce collagen and elastin?
If you are constantly under stress, it leads to the overproduction of the hormone cortisol, which makes it difficult for your skin to repair itself and continue to produce collagen and elastin. Be sure to get exercise, plenty of sleep, and avoid stress to reduce cortisol levels.
What is the function of elastin?
Elastin is a rubber-like protein that has elastic properties, as its name suggests. Elastin allows the skin to “snap back” to its original shape after being stretched or contracted. As your skin loses elastin, it is no longer able to bounce back, so if your skin gets stretched, it will remain stretched.
Why does skin get thinner over time?
Regardless of how well you care for your skin, your skin becomes thinner and less resilient over time. While intrinsic aging inevitably leads to wrinkle formation, it is when extrinsic aging occurs that the effects of aging skin are magnified. Extrinsic aging is often the result of poor lifestyle habits and environmental damage.
How to protect skin from elastin loss?
Protect your skin by wearing sunscreen with SPF 30 or higher every day to keep your skin looking its best and prevent elastin degradation from taking place . You should also avoid exposure to pollution, cigarettes, alcohol, drugs, pesticides, toxins, and stress, all of which lead to collagen and elastin loss.

As a consequence, elastin was conventionally described as an amorphous polymer.
Why is elastin insoluble?
Elastin is insoluble due to the cross-linking of amino acid chains. Tropoelastin is a precursor protein of elastin, and is composed of hydrophilic (lysine, valine and proline) and hydrophobic (glycine, valine and proline) domains.
What enzyme is responsible for cross linking soluble monomers into insoluble fibers?
The enzyme, lysyl oxidase, initiates cross-linking of the soluble monomers into insoluble fibers. Extracellular elastin associates closely with other proteins in the matrix, including microfibrillar proteins and collagens. Once laid down in the matrix, the insoluble protein is very stable and resistant to degradation.
What is the function of elastin?
It is located throughout many tissues and organs of higher vertebrates and plays an important functional role in maintaining pressures associated with liquid and air flow in the cardiovascular and pulmonary systems. Elastogenic cells synthesize and secrete a soluble monomeric form of elastin into the extracellular space. The enzyme, lysyl oxidase, initiates cross-linking of the soluble monomers into insoluble fibers. Extracellular elastin associates closely with other proteins in the matrix, including microfibrillar proteins and collagens. Once laid down in the matrix, the insoluble protein is very stable and resistant to degradation. Because of its critical role in the normal development and function of vital organs, either impairment of elastin synthesis or proteolytic degradation of the insoluble fibers results in major clinical pathologies.
What are the functionally critical properties of native elastins?

What are the amino acids in elastin?
Elastin and elastin-derived peptides that confer flexibility and distensibility to all tissues have been combined with various biological matrices to modulate their morphological, physical and biological characteristics.10 Elastin contains hydrophobic amino acids (proline, glycine, desmosine and isodesmosine) and a high degree of intermolecular cross-links which makes elastin fibers highly resistant to proteolytic degradation. Elastin fibers are able to recoil after stretching; furthermore, the long-term stability of the elastin fibers makes it a desirable protein for dynamic organ tissue engineering. Additionally, it has been reported that solubilized elastin can not only induce angiogenesis, but also increase elastic fiber synthesis.
What is the purpose of elastin?

Why is it important to have elastin in your lungs?
It is important for our veins and arteries to be able to adjust to the changes in pressure. The elasticity of the elastin protein allows for this adjustment. Organs such as our lungs greatly depend on elastin as well. With each breath, your lungs must expand and contract.
Why is elastin important?
Elastin is crucial in allowing our skin to go back into place after weight loss to some extent and to allow flexing of the skin as we exercise. As we age, the amount of elastin produced by our bodies decreases, resulting in wrinkling of the skin and sagging in some places.
Why does my arm snap back into place?
If you pinch the skin on your arm and then release it, you'll notice that it snaps back into place. Your skin is able to do this because it contains elastin . This is a very important quality - just imagine the trouble and difficulty you would have if your skin could not snap back into its rightful place.
What happens to the lungs after each breath?
With each breath, your lungs must expand and contract. The elastin found in the tissues of the lungs allows them to return to their original shape after each breath. If our lungs were not able to do this, we would not be able to survive. It is also normal for us to gain and lose weight throughout our lives.

The feasibility of using recombinant human tropoelastin to enable elastin fiber production to improve skin flexibility in wounds and scarring has been studied. After subcutaneous injections of recombinant human tropoelastin into fresh wounds it was found there was no improvement in scarring or the flexibility of the eventual scarring.
Biosynthesis
Elastin is made by linking together many small soluble precursor tropoelastin protein molecules (50-70 kDa), to make the final massive insoluble, durable complex. The unlinked tropoelastin molecules are not normally available in the cell, since they become crosslinked into elastin fibres immediately after their synthesis by the cell, after their export into the extracellular matrix.
Each tropoelastin consists of a string of 36 small domains, each weighing about 2 kDa in a rando…
Molecular biology
In mammals, the genome only contains one gene for tropoelastin, called ELN. The human ELN gene is a 45 kb segment on chromosome 7, and has 34 exons interrupted by almost 700 introns, with the first exon being a signal peptide assigning its extracellular localization. The large number of introns suggests that genetic recombination may contribute to the instability of the gene, leadin…
