Any of several heterooligomeric complexes containing multiple septins. An organelle found in cnidoblast (nematoblast) cells. When matured, these stinging organelles store toxins and can deliver them when the cnidocil (a short extension of the cnidocyst) is stimulated by a prey or another stimulus. Membrane associated dimeric protein (240 and 220 kDa) of erythrocytes. Forms a complex with ankyrin, actin and probably other components of the membrane cytoskeleton, so that there is a mesh of proteins underlying the plasma membrane, potentially restricting the lateral mobility of integral proteins. A cytoskeletal structure composed of actin filaments and myosin that forms beneath the plasma membrane of many cells, including animal cells and yeast cells, in a plane perpendicular to the axis of the spindle, i.e. the cell division plane. Ring contraction is associated with centripetal growth of the membrane that divides the cytoplasm of the two daughter cells. In animal cells, the contractile ring is located inside the plasma membrane at the location of the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms beneath the plasma membrane at the mother-bud neck before mitosis. The region that lies just beneath the plasma membrane on the basal edge of a cell. A tight ring-shaped structure that forms in the division plane at the site of cytokinesis; composed of members of the conserved family of filament-forming proteins called septins as well as septin-associated proteins. This type of septin structure is observed at the bud neck of budding fungal cells, at the site of cell division in animal cells, at the junction between the mother cell and a pseudohyphal projection, and also within hyphae of filamentous fungi at sites where a septum will form. A discrete actin-containing structure found at the plasma membrane in cells, at sites of endocytosis; formed of networks of branched actin filaments that lie just beneath the plasma membrane and assemble, move, and disassemble rapidly. An example of this is the actin cortical patch found in Saccharomyces cerevisiae. Any of the large immobile protein assemblies at the plasma membrane that mark endocytic sites. In yeast, S. cerevisiae, these structures are primarily composed of Pil1p and Lsp1p. Polarized accumulation of cytoskeletal proteins (including F-actin) and regulatory proteins in a cell. An example of this is the actin cap found in Saccharomyces cerevisiae. Protein complex that plays a role in determining cell polarity by directing the localized assembly of actin filaments at polarization sites; in Saccharomyces the polarisome includes Bni1p, Spa2p, Pea2p, and Bud6p. A dense network of actin filaments found beneath the apical cell surface of hair cells, and into which stereocilia are inserted. A high molecular weight complex characterized in S. pombe containing the cell-end anchoring protein Tea1. This complex is transported to the cell ends by microtubules and is involved in bipolar growth and the maintennce of normal cell polarity. Any of a series of structures composed of septins and septin-associated proteins localized to the cleavage plane which are involved in cytokinesis. The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell. Any constituent part of the cytoplasm, all of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. A protein complex peripherally associated with the plasma membrane that determines where vesicles dock and fuse. At least eight complex components are conserved between yeast and mammals. The region that lies just beneath the plasma membrane on the apical edge of a cell. Any constituent part of the cell cortex, the region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins. Arrays of microtubules underlying and connected to the plasma membrane in the cortical cytosol. The portion of the cytoskeleton that lies just beneath the plasma membrane. Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins. A medial cortical band overlaying the nucleus which acts as a landmark for contractile ring positioning and plays a role in cell cycle regulation.
