Intermediate filaments: a dynamic network that controls cell mechanics
In humans the superfamily of intermediate filament (IF) proteins is encoded by more than 70 different genes, which are expressed in a cell- and tissue-specific manner. IFs assemble into approximately 10 nm-wide filaments that account for the principal structural elements at the nuclear periphery, nucleoplasm, and cytoplasm. They are also required for organizing the microtubule and microfilament...
متن کاملIntermediate filaments and disease: mutations that cripple cell strength
T HERE are nearly 50 different intermediate filament (IF) proteins of five major types (for reviews, see references 16, 23, and 59). Four of the IF types are cytoplasrnic, and they are expressed differentially in all tissues at various stages of embryonic and adult development. Type V IF proteins are the nuclear lamins, which form a fibrous meshwork on the inner surface of the nuclear membrane,...
متن کاملCorrection: Attractive Interactions among Intermediate Filaments Determine Network Mechanics In Vitro
Mechanical and structural properties of K8/K18 and vimentin intermediate filament (IF) networks have been investigated using bulk mechanical rheometry and optical microrheology including diffusing wave spectroscopy and multiple particle tracking. A high elastic modulus G0 at low protein concentration c, a weak concentration dependency of G0 (G0 ∼ c(0.5 ± 0.1)) and pronounced strain stiffening a...
متن کاملHierarchical Structure Controls Nanomechanical Properties of Vimentin Intermediate Filaments
Intermediate filaments (IFs), in addition to microtubules and microfilaments, are one of the three major components of the cytoskeleton in eukaryotic cells, playing a vital role in mechanotransduction and in providing mechanical stability to cells. Despite the importance of IF mechanics for cell biology and cell mechanics, the structural basis for their mechanical properties remains unknown. Sp...
متن کاملIntermediate filaments
Intermediate filaments form a class of insoluble cytoplasmic filaments ofdimensions intermediate in size between those of microtubules (about 25 nm in diameter) and microfilaments (about 7 nm in diameter). Thus, they are generally known as intermediate-sized filaments (IF)' or 10-nm filaments. They have been identified in virtually all differentiated types ofcells and it seems possible that IF-...
