Recent research published in the Proceedings of the National Academy of Sciences reveals vital insights on vimentin, a protein crucial for maintaining cell shape and aiding wound healing. The study highlights a previously unexamined variant of vimentin, showing its ability to form liquid-like droplets that interact with actin fibers. This interaction not only protects actin from disassembly but also enhances our understanding of cellular mechanics and has potential implications for cancer metastasis and other essential biological phenomena.
"In previous research, vimentin turned out to have a novel structure that could explain some of its unique physical properties," Adam said.
"Surprisingly, we also found that the droplets coat the actin filaments in the cell in a physical process called wetting and protect the actin filaments from disassembly..." Adam said.
