Collagen receptors and collagen-binding proteins

Collagen, the most abundant protein in the body, has an obvious structural role, as in bone, tendon and skin, serving as a scaffold upon which the extracellular matrix assembles.  Several cell-surface collagen receptors also allow collagen to regulate cell behaviour.

Over the past few years we have produced the Collagen Toolkits, overlapping synthetic triple-helical peptides (THPs) that span the entire triple-helical (Col) domains of collagens II and III.  These peptide libraries allow us to map within collagen the interaction sites of collagen binding receptors and matrix components.  We work primarily on the collagen-binding integrins, α1β1, α2β1, α10β1 and α11β1, and on immune receptors related to Glycoprotein (Gp) VI, LAIR1 and OSCAR, as well as on the discoidin domain receptors, DDR1 and DDR2.  Our interests are broadening further to include, for example, matrix metalloproteinases, fibronectin and a diverse set of bacterial adhesins.

We collaborate widely in this activity, and have set up a website to facilitate access to our materials and expertise:

We design specific THP ligands for the above, and are working to use these as components of biomaterials.  The group has a long-standing interest in thrombus deposition on collagens of the blood vessel wall, mediated directly by platelet Gp VI and integrin α2β1, and indirectly by von Willebrand factor/Gp Ib.

Current funding for the group is through Programme, Special Project and Studentship support from British Heart Foundation (all expiring during 2018).
