Abstract:

The pentraxins, serum amyloid P component (SAP) and C-reactive protein (CRP) are target proteins for the development of treatments for amyloidosis and ischaemic injury, respectively, in humans. This study reports the first multivalent ligands capable of targeting all five SAP binding sites simultaneously. Ligands presenting five or ten D-proline headgroups and composed of five peptideglycol linkers emanating from ε-N-substituted lysine residues on a central cyclic peptide core were synthesised by solid phase peptide synthesis. The sub-nanomolar, ~250pM, binding affinity approximated by Isother

Abstract:

Integrins are a large family of αβ heterodimeric cell surface receptors that interact with the extracellular matrix and/or counter-receptors on other cells. These interactions control the adhesion and migration of cells as well as regulating numerous signal transduction pathways. Integrins exist in low and high affinity states, subject to allosteric regulation. Integrin-ligand recognition is divalent cation-dependent and mediated by the α subunit N-terminal repeats, the β subunit I domain and in certain integrins, the α subunit I domain. Two competing models based upon structure predictions, t

Abstract:

Molecular Dynamics (MD) and Quartz Crystal Microbalance (QCM) techniques can provide unique insights into what drives protein-ligand association. The major urinary protein (MUP) binds small ligands in a deeply buried hydrophobic pocket. Detailed calorimetric studies have shown that ligand binding is driven by enthalpic effects, not entropic effects [1]. Previous studies have shown that this is due to 'dewetting' of the binding site cavity even in the absence of ligands, and have also characterised the complex changes in molecular flexibility that accompany ligand binding-features that may be c

Abstract:

Molecular recognition is a fundamental step in essentially any biochemical process. Detailed structural knowledge is crucial to have a better understanding of the processes in which the two interacting molecular partners are involved and can be exploited in several applied fields such as supramolecular design of new molecular assemblies, rational drug design, and enzyme engineering. In the context of molecular recognition, I have investigated (mainly by single crystal x-ray crystallography) some relevant protein-protein and protein-ligand systems in order to gain detailed structural insights

Abstract:

Mammalian odorant receptors (ORs) are Class I G-protein coupled receptors (GPCRs) located within the nasal epithelium. Odorant receptors interact with Galpha olfactory, a Galpha S type G-protein. Activated Galpha olfactory stimulates adenylate cyclase and the resulting increase in cAMP concentration opens cyclic nucleotide gated channels allowing Ca2+ to enter the cell. The increased Ca2+ then activates a Ca2+ activated Cl- channel which further depolarizes the cell. This depolarization initiates an action potential that reaches the axon of the olfactory sensory neuron located in the main

Ligand-protein binding models have experienced an evolution during time: from the lock-key model to induced-fit and conformational selection, the role of protein flexibility has become more and more relevant. Understanding binding mechanism is of great importance in drug-discovery, because it could help to rationalize the activity of known binders and to optimize them. The application of computational techniques to drug-discovery has been reported since the 1980s, with the advent computer-aided drug design.

The information obtained by using these algorithms couldcontribute to the development of new drugs by generating new ligands that target specifichigh-energy, unfavorable waters.

Lectin-like oxidised low-density lipoprotein receptor-1 (LOX-1) is a scavenger receptor that binds a wide range of ligands including oxidised low-density lipoprotein (OxLDL).

The C-type lectin-like domain of LOX-1 binds OxLDL but the molecular basis for this recognition is unclear. Glycosidase or protease-mediated removal of exposed N-linked carbohydrates or protein epitopes on OxLDL led to the conclusion that LOX
