Vimentin
Vimentin
Vimentin (pronounced vih-MEN-tin) is a type of intermediate filament (IF) protein that is expressed in mesenchymal cells. It plays a crucial role in maintaining cellular integrity and providing resistance against stress.
Etymology
The term "Vimentin" is derived from the Latin word 'vimentum', which means 'binding' or 'connecting'. This is reflective of the protein's role in connecting different parts of a cell and maintaining its structural integrity.
Function
Vimentin is a key component of the cytoskeleton, which provides a framework for the cell and is involved in many crucial cellular processes. It is particularly important in cells that are subject to mechanical stress, as it helps to absorb shock and prevent damage. Vimentin also plays a role in cell division, migration, and signaling.
