Descriptions Names[Advanced Search]

Any constituent part of the cytoskeleton, a cellular scaffolding or skeleton that maintains cell shape, enables some cell motion (using structures such as flagella and cilia), and plays important roles in both intra-cellular transport (e.g. the movement of vesicles and organelles) and cellular division. Includes constituent parts of intermediate filaments, microfilaments, microtubules, and the microtrabecular lattice. The part of the cortical actin cytoskeleton that forms part of a macropinocytic cup. A cell projection that forms at the site of macropinocytosis, a form of endocytosis that results in the uptake of relatively large amounts of extracellular fluid. The macropinocytic cup membrane selectively excludes certain proteins, such as H36 or PM4C4 in Dictyostelium, and the underlying cytoskeleton is enriched in F-actin and coronin. Any constituent part of a cell, the basic structural and functional unit of all organisms. The portion of the cytoskeleton that lies just beneath the plasma membrane. The portion of the actin cytoskeleton, comprising filamentous actin and associated proteins, that lies just beneath the plasma membrane. Any constituent part of a cell projection, a prolongation or process extending from a cell, e.g. a flagellum or axon. A prolongation or process extending from a cell, e.g. a flagellum or axon. The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.
