Abstract:
The p53 tumour suppressor protein has presented a challenge for structural biology for more than two decades. The complete p53 molecule has eluded numerous attempts to determine its structure, presumably owing to the intrinsic conformational flexibility that is essential to the protein's function. Recent data obtained by X-ray crystallography, NMR spectroscopy and electron microscopy provide new insight into the quaternary architecture of the whole molecule and new strategies for examining how these structures correlate with the cell and molecular biology of the 'Guardian of the Genome'.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
