Collagen is a protein present in all the bodyâs organs and tissues. It provides the matrix that sustains the bodyâs structure. Collagenâs main function is to sustain tendons, skin and cartilage. It provides integrity, firmness and elasticity to their structures.
The COL1A1 gene provides instructions for making part of a large molecule called type I collagen. Collagens are a family of proteins that strengthen and support many tissues in the body, including cartilage, bone, tendon, skin, and the white part of the eye (the sclera).ype I collagen is the most abundant form of collagen in the human body. The COL1A1 gene produces a component of type I collagen called the pro-Î±1(I) chain. Collagens begin as procollagen molecules, which must be processed by enzymes outside the cell to remove extra protein segments from their ends.
