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. A complex of gamma tubulin and associated proteins thought to be formed by multimerization of gamma-tubulin small complexes located at equatorial microtubule organizing centers. Any constituent part of the cytoplasm, all of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. A cytoplasmic structure that can catalyze gamma-tubulin-dependent microtubule nucleation and that can anchor microtubules by interacting with their minus ends, plus ends or sides. Any constituent part of the cell division plane, the eventual plane of cell division in a dividing cell. Any constituent part of a cell, the basic structural and functional unit of all organisms. The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins. The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. The cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane. The mitotic, or meiotic, spindle is aligned perpendicular to the division plane. A microtubule organizing center formed by a band of gamma-tubulin that is recruited to a circumferential band of F-actin at the midpoint of a cell and which nucleates microtubules from the cell division site at the end of mitosis.
