The primary function of COL1A2 is to form type I collagen fibers. Type I collagen is a heterotrimer, composed of two alpha-1 chains (encoded by the COL1A1 gene) and one alpha-2 chain (encoded by the COL1A2 gene). These collagen molecules assemble into long fibrils, which provide structural support and tensile strength to connective tissues. The proper assembly of these fibrils is essential for the integrity and function of various tissues.
