摘要：

1. 1. Soluble Type I-like collagens were isolated from the dermis and peritoneum of hagfish, a member of the cyclostomes. These tissue collagens had the typical heterotrimeric nature of (α1)2α2, but were genetically distinct from each other. 2. 2. Characterization of soluble and pepsin-solubilized Type I-like collagens from various tissues of hagfish revealed the tissue-specific existence of two different molecular species; one was designated skin collagen which existed in dermis and esophagus and the other was designated body collagen which was distributed in peritoneum, muscle and intestine. 3. 3. The skin collagen had a strong resemblance to shark skin Type I collagen, while the body collagen was rather similar to invertebrate Type I-like collagens. © 1989.
