A process that maintains the mitotic actinomyosin contractile ring at the plasma membrane.

Any actomyosin contractile ring assembly that is involved in mitotic cytokinesis.

The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein.

The directed movement of the endoplasmic reticulum to the site where a cell will divide.

A protein modification process in which one or more groups of a small protein, such as ubiquitin or a ubiquitin-like protein, are covalently attached to or removed from a target protein.

An endocytosis process that begins when material is taken up into clathrin-coated pits, which then pinch off to form clathrin-coated endocytic vesicles.

Any process that activates or increases the frequency, rate or extent of mitotic division septum formation. Division septum formation is the assembly and arrangement of a septum that spans the plasma membrane interface between progeny cells following cytokinesis.

Any actomyosin contractile ring maintenance that is involved in mitotic cell cycle.

Any actomyosin contractile ring assembly that is involved in mitotic cytokinesis.

Any protein localization to cell division site that is involved in mitotic actomyosin contractile ring assembly.

Any protein localization to cell division site that is involved in mitotic actomyosin contractile ring assembly.

Any protein localization to cell division site that is involved in mitotic actomyosin contractile ring assembly.

Any process that stops, prevents, or reduces the frequency, rate or extent of ubiquitin-specific protease (deubiquitinase) activity.

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 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. In animal cells, the contractile ring is located at the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms at the mother-bud neck before mitosis.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The component of the plasma membrane consisting of gene products and protein complexes with covalently attached hydrophobic anchors products that penetrate only the cytoplasmic side of the membrane.

The region of the actomyosin ring adjacent to the plasma membrane where membrane bound scaffolds are located.

A vacuole to which materials ingested by endocytosis are delivered.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

An endocytic patch that consists of an actin-containing structure found at the plasma membrane in cells; 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.

The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.

A sterol-rich region of the plasma membrane which forms at the cell surface overlying the contractile ring and spreads into the invaginating plasma membrane surrounding the septum.

The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.

The region at the end of the longest axis of a cylindrical or elongated cell.

A component of the cell division site that contains the mid1, cdr2, wee1, klp8, and blt1 proteins, and is involved in contractile ring localization. Medial cortical node complexes appear as cortical dots in the middle of the cell during interphase, and function to recruit other ring components in early mitosis.

A cytoskeletal structure composed of actin filaments, myosin, and myosin-associated proteins that forms beneath the plasma membrane of many cells, including animal cells and yeast cells, in a plane perpendicular to the axis of the mitotic spindle, i.e. the cell division plane. Ring contraction is associated with centripetal growth of the membrane that divides the cytoplasm of the two future daughter cells. In animal cells, the mitotic 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 mitotic contractile ring forms beneath the plasma membrane at the mother-bud neck before mitosis.
