By the use of complement fixation and in vivo immunofluorescence with cross-absorption studies it was shown that acid soluble collagens prepared from rat, mouse, guinea pig, chicken, carp, and man exhibit species specificity. Rat and mouse collagens were found to be indistinguishable and to cross-react with guinea pig collagen. Cross-reactions also occurred between the collagens of rat and man ...

Unconventional collagens are nonfribrillar proteins that not only contribute to the structure of extracellular matrices but exhibit unique bio-activities. Although roles for unconventional collagens have been well-established in the development and function of non-neural tissues, only recently have studies identified roles for these proteins in brain development, and more specifically, in the f...

Minor fibrillar collagens are recognized as the organizers and nucleators during collagen fibrillogenesis but likely serve additional functions. The minor fibrillar collagens include collagens type V and XI. Mutations of collagens type V and XI can cause Ehlers-Danlos, Stickler's, and Marshall's syndromes in human. We have characterized the spatiotemporal expression patterns of Col11a1, Col11a2...
