elastin

 [e-las´tin]
a yellow scleroprotein, the essential constituent of elastic connective tissue; it is brittle when dry, but flexible and elastic when moist.

e·las·tin

(ē-las'tin), [MIM*130160]
A yellow elastic fibrous mucoprotein that is the major connective tissue protein of elastic structures (for example, large blood vessels, tendons, ligaments); elastins precursor is proelastin.
Synonym(s): elasticin

elastin

A fibrous protein which is similar to collagen (in that one-third of the amino acids are glycine) with abundant proline, valine, and arginine, and which is formed by cross-linking small globular subunits to lysine residues. Elastin’s elasticity is ideally suited for its prominent role in arterial walls, vocal cords, alveolar septa, and ligaments, and has an amorphous wavy appearance by light microscopy. Defects in the cross-linking in elastin’s unique beta spiral, as well as increases or decreases in elastin, are implicated in coronary heart disease, emphysema, type-V Ehlers-Danlos syndrome, Menke’s kinky hair disease, pseudoxanthoma elasticum, and X-linked cutis laxa.
