Proceedings of the National Academy of Sciences of the United States of America, Vol. 74, No. 2 (Feb., 1977), pp. 662-665 (4 pages) Guinea pig vascular endothelial cells contain naturally occurring ...

When ultrathin frozen sections of chicken cardiac muscle were osmicated, dehydrated in ethanol, embedded in ethyl cellulose, and stained with acidic uranyl acetate, filaments of 10-12 nm width were ...

The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes ...

Intermediate filaments (IFs) are assembled from fibrous proteins that exhibit a central α-helical rod domain with a conserved substructure. This rod domain facilitates the formation of dimeric ...

Just as the skeleton and muscles move the human body and hold its shape, the cells of the body are stabilized and moved by a cellular skeleton. This cellular skeleton is a dynamic structure, ...

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

Biologists have found a unique version of a filament-forming protein in human cells that insects lack. Providing structural support and protection against such conditions as blistering, cataracts and ...

Neurofilament light (NfL) is a 68 kDa cytoskeletal intermediate filament protein highly expressed in neuronal axons. It is associated with the 125 kDa Neurofilament medium (NfM) and the 200 kDa ...

Glial Fibrillary Acidic Protein (GFAP) is a class-III intermediate filament that is mostly produced in astrocytic glial cells in the central nervous system. Astrocytes have important functions in ...
