Collagen is also abundant in corneas, blood vessels, the gut, intervertebral discs, and the dentin in teeth. [3] In muscle tissue, it serves as a major component of the endomysium. Collagen constitutes 1% to 2% of muscle tissue and 6% by weight of skeletal muscle. [4] The fibroblast is the most common cell creating collagen in animals.
Collagen XVII is a homotrimer of three alpha1(XVII)-chains [11] and a transmembrane protein in type II orientation. Each 180 kD a-chain contains a globular intracellular domain of approximately 70 kDa, which interacts with beta4-integrin, plectin, and BP230 [12] [13] and is necessary for the stable attachment of hemidesmosomes to keratin intermediate filaments.
This gene encodes the alpha-1 chain of type II collagen, a fibrillar collagen found in cartilage and the vitreous humor of the eye. Mutations in this gene are associated with achondrogenesis, chondrodysplasia, early onset familial osteoarthritis, SED congenita, Langer-Saldino achondrogenesis, Kniest dysplasia, Stickler syndrome type I, and spondyloepimetaphyseal dysplasia Strudwick type.
Collagen alpha-1(IV) chain (COL4A1) is a protein that in humans is encoded by the COL4A1 gene on chromosome 13. [ 5 ] [ 6 ] It is ubiquitously expressed in many tissues and cell types. [ 7 ] COL4A1 is a subunit of the type IV collagen and plays a role in angiogenesis . [ 8 ]
It is a rigid, non-soluble, fibrous protein that adds up to one-third of the proteins in the human body. Collagen is mostly made up of molecules packed together to form long and thin fibrils that support each other and ensure the skin is strong and elastic. [2] Various types of collagens have individual roles and structures.
