Collagen type III also known as COL3 and collagen III is a fibrillar protein with an approximate molecular mass of 138 kDa. This protein is a significant component of the extracellular matrix and is mainly expressed in connective tissues like skin lungs and vascular walls. You can also find it in developing tissues and fibrotic tissues reflecting its role during tissue growth and repair processes.
Biological function summary
Collagen type III contributes to maintaining the structural integrity of tissues. It forms a complex with collagen type I providing a scaffold that ensures mechanical strength and stability to tissues. This structural pairing of collagen type I and III highlights their cooperative function in supporting the extracellular matrix and regulating cell behavior in tissue repair and wound healing processes.
Pathways
Collagen type III is integral to the processes of tissue repair and fibrosis pathways. It interacts closely with proteins such as fibronectin and integrins contributing to the cellular adhesion and signaling pathways important for fibroblast function and migration. These interactions reflect its essential role in matrix assembly and stability influencing how cells respond to injury and repair damaged tissues.
Collagen type III mutations or dysregulation associate with vascular Ehlers-Danlos syndrome and keloids. In vascular Ehlers-Danlos syndrome defective collagen III compromises vessel wall integrity resulting in vascular fragility and rupture. In the context of keloids excessive collagen III accumulation in the skin illustrates its role in pathological fibrosis. Collagen type I is another protein that plays an important role in these conditions contributing along with collagen type III to the altered structural and functional properties observed in these disorders.
