The COL2A1 gene provides instructions for making the basic component of type II collagen, called the alpha-1(II) chain. Type II collagen adds structure and strength to connective tissues and plays an important role in the normal development of joints, eyes, and the inner ear.
Normal function
The COL2A1 gene provides instructions for making the basic component of type II collagen, called the alpha-1(II) chain. Type II collagen adds structure and strength to connective tissues and plays an important role in the normal development of joints, eyes, and the inner ear.
Type II collagen is found primarily in cartilage, a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later replaced by bone, except for the cartilage that covers and protects the ends of bones and the cartilage that is present in the nose and external ears. Type II collagen is particularly abundant in a form of cartilage known as hyaline cartilage, which is found in the developing skeleton, joints, and at the end of the long bones of the arms and legs where new bone is produced (growth plates). Type II collagen is also part of the inner ear, the clear gel that fills the eyeball (the vitreous), and the center portion (nucleus pulposus) of the discs between the bones of the spine (vertebrae).
To construct type II collagen, three alpha-1(II) chains twist together to form a procollagen molecule. Procollagen molecules are then processed by enzymes in the cell. Once processed, the modified collagen molecules leave the cell and arrange themselves into long, thin fibrils that attach (bind) to one another in a lattice pattern (cross-link) in the spaces around cells. The cross-linkages result in the formation of very strong, mature type II collagen fibers.
