Project Summary

The consortium brings together scientists from the universities of Dundee, Liverpool, Manchester, Oxford, East Anglia and Imperial College London. The project officially began in May 2004 with an award of £3.5M from the Research Councils UK Basic Technology programme.

Carbohydrates interact with proteins in many biological processes such as fertilization, virus infections and even tumor growth. Therefore, structural and functional aspects concerning the interplay of the glycome (the complete set of carbohydrate structures produced by a particular cell or tissue) and the proteome (set of proteins) are of great interest in biology and medicine.

The aim of the present project is to develop carbohydrate arrays (glycoarrays) as innovative tools to map out the carbohydrate and protein partners in these highly specific interactions of the glycome. The project brings together a diverse set of novel technologies: from the generation of carbohydrate libraries (from natural sources, by chemical and enzymatic synthesis) and finding ways of linking the saccharides to a surface, to high throughput expression of carbohydrate binding proteins and the analysis of carbohydrate-protein binding by mass spectrometry, surface plasmon resonance and fluoresence measurements.

An understanding of the cell's glycome-protein interactions complements data from studies of the proteome and represents an essential facet of post-genome technology development that will underpin exploitation through development of novel glycotherapeutics in diverse applications such as cancer, infectious diseases, inflammation, neurodegeneration, wound healing and tissue engineering.

The RCUK Basic Technology webpage for this project is entiteled 'A sweet tool for glycome studies'
