What to know about Cells remodel actin normally without coronins, challenging textbook view

Researchers at the University of Basel have published a study in PLOS Biology challenging the long-held scientific view that coronin proteins are essential regulators of the actin cytoskeleton. The study suggests that previous findings may have been influenced by experimental artifacts and proposes that coronins play a more significant role in cell signaling.

What happened

Cells remodel actin normally without coronins, challenging textbook view Swati Mestri Scientific Editor Robert Egan Senior Editor Coronins are found throughout the animal kingdom, from single-celled amoebae to humans, and are involved in many vital processes,…

Why it matters

For decades, textbooks and hundreds of scientific papers have described coronins primarily as proteins that bind to actin, a key component of the cytoskeleton.

Common ground

Because of this presumed interaction, coronins have long been regarded as regulators of the cytoskeleton—a network of actin filaments that gives cells their shape, enables them to move and helps organize their contents.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
