Cytoskeleton, a system of filaments or fibers that is present in the cytoplasm of eukaryotic cells. The cytoskeleton organizes other constituents of the cell, maintains the cell’s shape, and is responsible for the locomotion of the cell itself and the m
protein filaments and motor proteins that help in cell movement. it provides shape and support to the cell, organizes the organelles and facilitates transport of molecules, cell division and cell signalling. let us have a detailed look at the structure and function of cytoskeleton. also read: ...
Microtubules also give the cellpolarity, which means the cell has two unique sides, or poles. This polarity is part of what makes it possible for the cell to organize its components, such as organelles and other portions of the cytoskeleton, because it gives the cell a way to orient those ...
Although plant cells contain intermediate filament proteins, their biochemical nature and their role in plant cell structure have not been determined. All three cytoskeletal components may contain additional specific proteins that contribute to their function and connect them with each other or with other...

MicroRNAs are proving to be fundamentally important for how organisms develop and function. Ambros and Ruvkun were interested in genes that control the timing of activation of different genetic programs, ensuring that various cell types develop at the right time. They studied two mutant strains of ...
Cell-cell contact is likely to play a significant role in regulating cell vitality, but its function is easily masked by cell-substrate interactions, thus remains incompletely characterized. In the first part of this thesis, we developed an enzyme-based whole cell sheet lifting method and ...
