Microtubules are the only structural constituent of the spindle apparatus required for induction of cell cleavage.Structural constituents of the spindle apparatus essential for cleavage induction remain undefined. Findings from various cell types using different approaches suggest the importance of ale ...
Microtubules are constituents of all eucaryotic cells. As such, they are composed of proteins that are highly conserved from the point of view of evolution. The machinery of the mitotic apparatus is formed of microtubules. The movement of cilia, flagella, and sperm tails depends on axonemal arra...
Ubiquitin is a component of paired helical filaments in Alzheimer's disease Paired helical filaments (PHF), which constitute a distinct type of pathological neuronal fiber, are the principal constituent of neurofibrillary tangles t... Mori HJ,J Kondo,Y Ihara - 《Science》 被引量: 1520发表: 1987...
Microtubules are the key structures required for the success of this operation, as they are the main constituents of mammalian bipolar spindles. Centrosomes also play an important role, being the primary source of microtubules. Although centrosomes are dispensable for the formation of bipolar spindles...
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 of elements that differ in size and in protein composition. Microtubules are the largest type of fila...
Kapitein1 Microtubules are hollow biopolymers of 25-nm diameter and are key constituents of the cytoskeleton. In neurons, microtubules are organized differently between axons and dendrites, but their precise organization in different compartments is not completely understood. Super-resolution microscopy ...
During prophase, body, while microtubules in the dendrites are of both the centrosome replicates, and each new centrosome orientations (Baas et al., 1988). As a result, different nucleates microtubules. The minus ends of the microtu- complements of cytoplasmic constituents are trans- bules ...
In previous studies it was shown that cytoplasmic microtubules are instrumental structures in the formation of radial-segmented (RS) nuclei in human lymphocytes and monocytes. The present study was concerned with the quantitative distribution of microtubule constituents in the cytoplasm of RS cells and ...
6A). This mode may suffice for starvation-induced autophagy, where the goal is to breakdown cytosolic constituents non-selectively to provide amino acids for the maintenance of essential cellular functions. Indeed, earlier studies have established that ribosomes and other cytoplasmic constituents are ...
Actin and tubulin are the two major proteins of the cytoskeleton in eukaryotic cells and both display a common property to reversibly assemble into long and flexible polymers, actin filaments and microtubules, respectively. These proteins play important roles in a variety of cellular functions and are...
