Carbohydrate Recognition in Cellular Function

Contributors to this volume explore the role of carbohydrates in communication between cells of multicellular organisms. Topics covered include the thermodynamics and spatial restrictions of oligosaccharide-protein interactions, the role of carbohydrates in recognition and as components of cell adhesion molecules, and abnormal glycosylation in several disease states.

Carbohydrate Recognition in Cellular Function Chairman: E. Ruoslahti 1989 Cells interact with their environment and with neighbouring cells by an intricate array of molecular recognition events. This book explores the role of carbohydrates in communication between cells of multicellular organisms. The thermodynamics and spatial restrictions of oligosaccharide — protein interactions are discussed. An analysis of the amino acid sequences required for carbohydrate recognition and the use of a consensus sequence to identify potential carbohydrate-binding proteins are described. Carbohydrates are important components of the different families of Cell adhesion molecules; one example is the mammalian sperm receptor, where the species specificity of egg recognition is achieved by a particular class of oligosaccharides. Isolated gangliosides and galactosides also mediate recognition processes directly, in nerve cells at least; a specific ganglioside activates a membrane-bound protein kinase in neuroblastoma cells, triggering phosphorylation of several cell surface proteins; and the different subsets of rat dorsal root ganglion neurons express distinct sets of oligosaccharides which are recognized by binding proteins on dorsal root ganglion and spinal neurons. Modification of the carbohydrate moiety of glycoproteins is a frequent occurrence in certain diseases, including those of the immune system. Recent progress in understanding all these areas is described. The discussions after each presentation highlight work that remains to be done.
