title: An unexpected sequence homology between link proteins of the proteoglycan complex and immunoglobulin-like proteins.
abstract: The N-terminal sequence (residues 1-101) of trypsin-link protein from cartilage proteoglycan complex is reported: it presents structural homologies with the poly-Ig receptor and immunoglobulin domains.
