Motor Proteins: Tightening Your Belt with Myosin VI
New work shows that the motor protein myosin VI, acting through vinculin, plays a key role in the maturation of cadherin-based adherens junctions in epithelial cells.
متن کاملSynaptic Ribbon Conveyor Belt or Safety Belt?
The synaptic ribbon in neurons that release transmitter via graded potentials has been considered as a conveyor belt that actively moves vesicles toward their release sites. But evidence has accumulated to the contrary, and it now seems plausible that the ribbon serves instead as a safety belt to tether vesicles stably in mutual contact and thus facilitate multivesicular release by compound exo...
متن کاملTrajectory Research about the Rolling-Pin Belt Transmission
A new belt transmission mechanism, having the function of no-slip driving, is described in the paper. It is composed of pulleys with carved rails and belt with rolled pins spaced out on both sides. Firstly, the trajectory curve is deduced along which pins embedded in the pulley. And then, parametric relationships are established, which are about center offsets of two pulleys, working radius of ...
متن کاملTightening a Contract Refinement
Contract-based design is an emerging paradigm for correctby-construction hierarchical systems: components are associated with assumptions and guarantees expressed as formal properties; the architecture is analyzed by verifying that each contract of composite components is correctly refined by the contracts of its subcomponents. The approach is very efficient, because the overall correctness pro...
