Abstract:
:A fusion of mouse and human genetics has now proven that intermediate filaments form a flexible scaffold essential for structuring cytoplasm in a variety of cell contexts. In some cases, the formation of this scaffold is achieved through a newly identified family of intermediate-filament-associated proteins that form cross-bridges between intermediate filaments and other cytoskeletal elements, including actin and microtubules.
