Elastin

Elastin is a major protein component of tissues that require elasticity such as arteries, lungs, bladder, skin and elastic ligaments and cartilage. It is composed of soluble tropoelastin protein containing primarily, glycine and valine and modified alanine and proline residues. Tropoelastin is a ~65kDa protein that is highly cross-linked to form an insoluble complex. The most common interchain cross-link in elastins is the result of the conversion of the amine groups of lysine to reactive aldehydes by lysyl oxidase. This results in the spontaneous formation of desmosine cross-links.
