| Biochemical Properties | The cDNA sequence of collagen XVII encodes a type II integral transmembrane protein of 1497 amino acid residues.Structural component of hemidesmosomes,180-kDa bullous pemphigoid antigen (BP180), is a transmembrane protein.Collagen XVII exists in two molecular forms,i.e. as a full-length transmembrane homotrimer of three 180-kDa α1(XVII) chains and as a 120-kDa soluble form. The latter corresponds to the extracellular domain and is presumably released from the cell surface by furin-mediated proteolytic processing.Higher content of hydroxyproline residues in the C-terminal region.39 amino acid residues (positions 471–509) close to the transmembrane region can form a three-stranded coiled-coil that may play a role in assembly. |

| Significance of PTMs | During biosynthesis, collagen acquires a number of post-translational modifications, including lysine modifications, that are critical to the structure and biological functions of this protein.Specific hydroxylysine residues located in the helical domain of the molecule are glycosylated by the addition of galactose or glucose-galactose. |
|---|
| Additional Comments | Mutations in the collagen XVII gene,COL17A1, lead to junctional epidermolysis bullosa, a hereditary blistering skin disease with epidermal detachment from the basement membrane |
