This "push" signal is balanced by a "pull" signal, driven by the ubiquitin ligase, Siah2. Ubiquitin ligases facilitate the recycling of defunct proteins. Siah2 is the assigned ubiquitin ligase for ...

A Quick Refresher: Push-Pull Cable Driven Mechanisms But first: just what exactly are cable driven mechanisms? It turns out that this term refers to a huge class of mechanisms, so we’ll limit ...

He built a push-pull mechanism that uses braided fishing line to transfer motion to the robot arm’s wrist using Bowden tubes. The motors are mounted on the arm’s base, with a drum and two ...

Scientists at St. Jude Children's Research Hospital used fluorescent imaging techniques to track the sequence of molecular events that kickstart the migration of developing neurons, implicating an ...
