Message definition (Collagen)

==Characteristics==
Collagen is one of the long, [[fibrous protein|fibrous structural proteins]] whose functions are quite different from those of [[globular protein]]s, such as [[enzyme]]s. Tough bundles of collagen called ''collagen fibers'' are a major component of the [[extracellular matrix]] that supports most tissues and gives cells structure from the outside, but collagen is also found inside certain cells. Collagen has great [[tensile strength]], and is the main component of [[fascia]], [[cartilage]], [[ligament]]s, [[tendon]]s, [[bone]] and skin. Along with [[elastin]] and soft [[keratin]], it is responsible for skin strength and elasticity, and its degradation leads to [[wrinkle]]s that accompany [[aging]]. It strengthens [[blood vessel]]s and plays a role in [[biological tissue|tissue]] development. It is present in the [[cornea]] and lens of the eye in [[crystal]]line form. It may be one of the most abundant proteins in the fossil record, given that it appears to fossilize frequently, even in bones from the [[Mesozoic]] and [[Paleozoic]].

特徴

コラーゲンは長い繊維構造タンパク質の一つであり、その機能は酵素などの球状タンパク質とは全く異なる。コラーゲン線維と呼ばれる丈夫なコラーゲンの束は、ほとんどの組織を支え、細胞に外側から構造を与える細胞外マトリックスの主要な構成要素であるが、コラーゲンはある種の細胞内部にも存在する。コラーゲンは大きな引っ張り強度を持ち、筋膜、軟骨、靭帯、腱、骨、皮膚の主成分である。エラスチンや柔らかいケラチンとともに皮膚の強度と弾力性を担っており、その劣化は老化に伴うしわの原因となる。血管を強化し、組織の発達に関与する。眼の角膜や水晶体には結晶線状で存在する。中生代や古生代の骨でも頻繁に化石化することから、化石記録では最も豊富なタンパク質の1つかもしれない。
