Thalidomide and the immunomodulatory drug, lenalidomide, are therapeutically active in hematological malignancies. The ubiquitously expressed E3 ligase protein cereblon (CRBN) has been identified as the primary teratogenic target of thalidomide. Our studies demonstrate that thalidomide, lenalidomide and another immunomodulatory drug, pomalidomide, bound(More)
Paxillin and vinculin are cytoskeletal proteins that colocalise to focal adhesions, specialised regions of the cell involved in attachment to the extracellular matrix. These two molecules form part of a complex of proteins that link the actin network to the plasma membrane. Paxillin has been shown to bind directly in vitro to the C-terminal region of(More)
We have determined the complete sequence of chick brain alpha-actinin (892 amino acids; 107,644 Da). The sequence differs from that of smooth muscle alpha-actinin only in the region of the first EF-hand calcium-binding motif, where 27 residues in brain alpha-actinin are replaced by just 22 residues in the smooth muscle isoform. This probably accounts for(More)
The lipid-storing tissues of plants contain many small (0.2-1 microns) lipid (normally triacylglycerol) droplets which are surrounded and stabilized by a mixed phospholipid and protein annulus. The proteinaceous components of the lipid storage bodies are termed oleosins and are not associated with any other cellular structures. The major oleosins of(More)
The authors have designed and constructed a new type of actuation for a spherical robot. The proposed actuation system consists of a large number of individually inflatable rubber bladders covering a sphere. Inflation of one or more of these bladders imparts a moment to the sphere and coordinated inflation results in a directed motion. Further, the authors(More)
We describe an investigation of proteinuria using Pharmacia PhastSystemTM electrophoresis apparatus. The analysis of urinary proteins by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) of unconcentrated urine followed by silver staining took about 2 h and could clearly demonstrate tubular dysfunction or glomerular damage in urines with(More)
Binding of the cytoskeletal protein vinculin to talin is one of a number of interactions involved in linking F-actin to cell-matrix junctions. To identify the talin binding domain in vinculin, we expressed the NH2-terminal region of the molecule encoded by two closely similar, but distinct vinculin cDNAs, using an in vitro transcription translation system.(More)
We have mapped the vinculin-binding sites in the cytoskeletal protein talin as well as those sequences which target the talin molecule to focal contacts. Using a series of overlapping talin-fusion proteins expressed in E. coli and 125I-vinculin in both gel-overlay and microtitre well binding assays, we present evidence for three separable binding sites for(More)
We describe the purification of Urine Protein 1 (UP1), a 14-16 kDa protein which occurs in the urine of patients with renal failure, and therefore may originate from the plasma or kidney. Amino acid sequencing shows that UP1 has significant homology with rabbit uteroglobin, a secretory protein of the uterus (during pregnancy) and lungs (both sexes), and(More)
The cytoskeletal protein vinculin is a component of adherens-type junctions where it is one of a number of interacting proteins thought to link the cytoplasmic domain of adhesion receptors to F-actin. Vinculin has been shown to bind to at least three other cytoskeletal proteins, talin, paxillin and alpha-actinin. In this study, we further characterise the(More)
