title: Evidence for the existence of a diverse family of immunoglobulin-related recognition molecules.
abstract: All classes of molecule postulated to play a role in recognition or to have some structural homology to immunoglobulins were compared by the S delta Q index of differences in amino acid composition. The results suggest that there is a wide family of immunoglobulin-related molecules that includes vertebrate immunoglobulins, T cell receptors, MHC products, C-reactive proteins, and (some) invertebrate lectins.
