(A) In a cell, motility is initiated by an actin ... mediated by stress fibers. (D) Then, retraction fibers pull the rear of the cell forward. Dynamic networks of protein filaments give shape ...

Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

Now, as a postdoctoral researcher in Pekka Lappalainen’s lab, I will focus on LIM domain proteins and their function in stress fiber dynamics ... since found my passion for actin dynamics, and I hope ...
