Summary This gene encodes the alpha-3 chain, one of the three alpha chains of type VI collagen, a beaded filament collagen found in most connective tissues. The alpha-3 chain of type VI collagen is much larger than the alpha-1 and -2 chains. This difference in size is largely due to an increase in the number of subdomains, similar to von Willebrand Factor type A domains, that are found in the amino terminal globular domain of all the alpha chains. These domains have been shown to bind extracellular matrix proteins, an interaction that explains the importance of this collagen in organizing matrix components. Mutations in the type VI collagen genes are associated with Bethlem myopathy, a rare autosomal dominant proximal myopathy with early childhood onset. Mutations in this gene are also a cause of Ullrich congenital muscular dystrophy, also referred to as Ullrich scleroatonic muscular dystrophy, an autosomal recessive congenital myopathy that is more severe than Bethlem myopathy. Multiple transcript variants have been identified, but the full-length nature of only some of these variants has been described. [provided by RefSeq, Jun 2009].

What is the normal function of the COL6A3 gene?

The COL6A3 gene provides instructions for making one component of type VI collagen, which is a flexible protein that surrounds muscle cells. Specifically, the protein produced from the COL6A3 gene is the alpha(α)3(VI) chain of type VI collagen. This chain combines with two other types of α(VI) chains (the α1 and α2 chains) to make a molecule called a collagen VI monomer. Two collagen VI monomers attach (bind) together to form collagen VI dimers. Two dimers group together to form a larger molecule called a tetramer, which is the complete type VI collagen molecule.

Type VI collagen molecules form complex networks that make up a large portion of the extracellular matrix surrounding muscle cells. The extracellular matrix is an intricate lattice that forms in the space between cells and provides structural support. The extracellular matrix that surrounds muscle cells is necessary for muscle cell stability and growth. Type VI collagen networks play an especially important role in the extracellular matrix of muscle that is used for movement (skeletal muscle).
