Cadherins are calcium-dependent cell adhesion molecules containing extracellular repeats of approximately 110 amino acids. The three-dimensional structure of the amino-terminal repeat of mouse epithelial cadherin was determined by multidimensional heteronuclear magnetic resonance spectroscopy. The calcium ion was bound by a short alpha helix and by loops at(More)
The chemotaxis inhibitory protein of Staphylococcus aureus (CHIPS) is reported to bind to the receptors for C5a and formylated peptides and has been proposed as a promising lead for the development of new anti-inflammatory compounds. Here we have examined the receptor specificity and mode of action of recombinant CHIPS(28-149) and also the immune response(More)
TFIIB is an essential component of the machinery that transcribes protein-coding genes. The three-dimensional structure of the human TFIIB core domain (TFIIBc) has been determined using multidimensional heteronuclear magnetic resonance spectroscopy. The molecule consists of two direct repeats that adopt similar alpha-helical folds, conferring pseudo-twofold(More)
The evasion of the host immune response is central to the pathogenicity of Staphylococcus aureus, and is facilitated by the ability of the cell wall-associated protein A (SpA) to bind immunoglobulin G Fc fragments, thereby impeding phacocytosis and classical pathway complement fixation. SpA also acts as a B-cell superantigen through interactions with the(More)
General transcription factor TFIID consists of TATA box-binding protein (TBP) and TBP-associated factors (TAF(II)s), which together play a central role in both positive and negative regulation of transcription. The N-terminal region of the 230 kDa Drosophila TAF(II) (dTAF(II)230) binds directly to TBP and inhibits TBP binding to the TATA box. We report here(More)
Staphylococcal immunoglobulin-binding protein, Sbi, is a 436-residue protein produced by many strains of Staphylococcus aureus. It was previously characterized as being cell surface-associated and having binding capacity for human IgG and beta(2)-glycoprotein I. Here we show using small angle x-ray scattering that the proposed extracellular region of Sbi(More)
A simple method has been developed for screening solution conditions to determine conditions under which a protein is soluble at the high concentrations typically used for NMR spectroscopy. The method employs microdialysis cells or 'buttons'. The low sample volume (5 microliters) required for each microdialysis button permits testing of a wide range of(More)
The paralogous multifunctional adaptor proteins YAP and TAZ are the nuclear effectors of the Hippo pathway, a central mechanism of organ size control and stem cell self-renewal. WW domains, mediators of protein-protein interactions, are essential for YAP and TAZ function, enabling interactions with PPxY motifs of numerous partner proteins. YAP has single(More)
Vertebrates have a unique 3D body shape in which correct tissue and organ shape and alignment are essential for function. For example, vision requires the lens to be centred in the eye cup which must in turn be correctly positioned in the head. Tissue morphogenesis depends on force generation, force transmission through the tissue, and response of tissues(More)
