A COL4A1 gene provides instructions for making one component of type IV collagen, which is a flexible protein important in the structure of many tissues throughout the body. Specifically, this gene makes the alpha1(IV) chain of type IV collagen. This chain combines with another alpha1 chain and a different type of alpha (IV) chain called alpha2 to make a complete type IV collagen alpha1-1-2 molecule. Type IV collagen molecules attach to each other to form complex protein networks. These protein networks are the main component of basement membranes, which are thin sheet-like structures that separate and support cells in many tissues. Type IV collagen alpha1-1-2 networks play an important role in the basement membranes in virtually all tissues throughout the body, particularly the basement membranes surrounding the body's blood vessels (vasculature). The type IV collagen network helps the basement membranes interact with nearby cells, playing a role in cell movement (migration), cell growth and division (proliferation), cell maturation (differentiation), and the survival of cells.
