Like many other extracellular proteins, newly synthesized collagen molecules undergo post-translational processing inside the cell to convert them into their mature form; they are then secreted and self-assemble into fibrils in the extracellular space. Collagen is the most abundant protein in mammals, making about 25% of the total protein content in animals. It is a major component of the extracellular matrix (ECM) and plays a critical role in tissue structure and function.
