Collagen alpha-1(VI) chain is a protein that in humans is encoded by the COL6A1 gene. [5]
The collagens are a superfamily of proteins that play a role in maintaining the integrity of various tissues. Collagens are extracellular matrix proteins and have a triple-helical domain as their common structural element. Collagen VI is a major structural component of microfibrils. The basic structural unit of collagen VI is a heterotrimer of the alpha1(VI), alpha2(VI), and alpha3(VI) chains. The alpha2(VI) and alpha3(VI) chains are encoded by the COL6A2 and COL6A3 genes, respectively. The protein encoded by this gene is the alpha 1 subunit of type VI collagen (alpha1(VI) chain). Mutations in the genes that code for the collagen VI subunits result in the autosomal dominant disorder, Bethlem myopathy. [5]
Cathepsin A is an enzyme that is classified both as a cathepsin and a carboxypeptidase. In humans, it is encoded by the CTSA gene.
Collagen alpha-1(V) chain is a protein that in humans is encoded by the COL5A1 gene.
Collagen alpha-2(V) chain is a protein that in humans is encoded by the COL5A2 gene.
Collagen alpha-5(IV) chain is a protein that in humans is encoded by the COL4A5 gene.
Collagen alpha-2(IV) chain is a protein that in humans is encoded by the COL4A2 gene.
Laminin subunit gamma-2 is a protein that in humans is encoded by the LAMC2 gene.
Collagen alpha-1(X) chain is a protein that in humans is a member of the collagen family encoded by the COL10A1 gene.
Collagen alpha-2(VI) chain is a protein that in humans is encoded by the COL6A2 gene.
Inter-alpha-trypsin inhibitor heavy chain H1 is a protein that in humans is encoded by the ITIH1 gene.
Collagen alpha-3(VI) chain is a protein that in humans is encoded by the COL6A3 gene. This protein is an alpha chain of type VI collagen that aids in microfibril formation. As part of type VI collagen, this protein has been implicated in Bethlem myopathy, Ullrich congenital muscular dystrophy (UCMD), and other diseases related to muscle and connective tissue.

Collagen alpha-2(IX) chain is a protein that in humans is encoded by the COL9A2 gene.
Collagen alpha-3(IX) chain is a protein that in humans is encoded by the COL9A3 gene.
Collagen alpha-1(XII) chain is a protein that in humans is encoded by the COL12A1 gene.
Collagen alpha-2(VIII) chain is a protein that in humans is encoded by the COL8A2 gene. Mutations of the gene are linked to posterior polymorphous dystrophy type 2.
Collagen alpha-1(VIII) chain is a protein that in humans is encoded by the COL8A1 gene.
Voltage-dependent L-type calcium channel subunit beta-3 is a protein that in humans is encoded by the CACNB3 gene.
Phosphorylase b kinase regulatory subunit beta is an enzyme that in humans is encoded by the PHKB gene.
Collagen alpha-1(XVI) chain is a protein that in humans is encoded by the COL16A1 gene.
Collagen VI (ColVI) is a type of collagen primarily associated with the extracellular matrix of skeletal muscle. ColVI maintains regularity in muscle function and stabilizes the cell membrane. It is synthesized by a complex, multistep pathway that leads to the formation of a unique network of linked microfilaments located in the extracellular matrix (ECM). ColVI plays a vital role in numerous cell types, including chondrocytes, neurons, myocytes, fibroblasts, and cardiomyocytes. ColVI molecules are made up of three alpha chains: α1(VI), α2(VI), and α3(VI). It is encoded by 6 genes: COL6A1, COL6A2, COL6A3, COL6A4, COL6A5, and COL6A6. The chain lengths of α1(VI) and α2(VI) are about 1,000 amino acids. The chain length of α3(VI) is roughly a third larger than those of α1(VI) and α2(VI), and it consists of several spliced variants within the range of 2,500 to 3,100 amino acids.
