Vezatin, a novel transmembrane protein, bridges myosin VIIA to the cadherin-catenins complex
2000
International audience; Defects in myosin VIIA are responsible for deafness in the human and mouse. The role of this unconventional myosin in the sensory hair cells of the inner ear is not yet understood. Here we show that the C-terminal FERM domain of myosin VIIA binds to a novel transmembrane protein, vezatin, which we identi®ed by a yeast two-hybrid screen. Vezatin is a ubiquitous protein of adherens cell±cell junctions, where it interacts with both myosin VIIA and the cadherin±catenins complex. Its recruitment to adherens junctions implicates the C-terminal region of a-catenin. Taken together, these data suggest that myosin VIIA, anchored by vezatin to the cadherin±catenins complex, cre…
The Largest Synthetic Structure with Molecular Precision: Towards a Molecular Object
2010
Pushing the limits: A 200A - 10 Da structurally defined, linear macromolecule (PG5) has a molar mass, cross-section dimension, and cylindrical shape that are comparable to some naturally occurring objects, such as amyloid fibrils or certain plant viruses. The macromolecule is resistant against flattening out on a surface; the picture shows PG5 embracing the tobacco mosaic virus (TMV).
