Does the genetic type of collagen determine fibril structure
A number of genetic types of collagen, all triple-helical but with significant variations in their amino acid sequences, have been found and the distribution of these genetic types is tissue specific. For example, tendon is composed only of type I collagen, while cartilage contains largely type II collagen. Skin contains a large amount of type I, but has a significant fraction, approx. 15%, of type III. Each of these types can form fibrils, but it is not known whether they form distinctive fibril structures that are important in determining tissue organization. We are using x-ray diffraction to analyze a variety of tissues with different collagen genetic types to compare the fibril structures and thus investigate whether genetic type is an important determinant of this structure.
