mitotic nuclear division

A cell cycle process comprising the steps by which the nucleus of a eukaryotic cell divides; the process involves condensation of chromosomal DNA into a highly compacted form. Canonically, mitosis produces two daughter nuclei whose chromosome complement is identical to that of the mother cell.

anaphase-promoting complex-dependent catabolic process

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 ubiquitin, with ubiquitin-protein ligation catalyzed by the anaphase-promoting complex, and mediated by the proteasome.

GO:0042787

protein ubiquitination involved in ubiquitin-dependent protein catabolic process

The process in which a ubiquitin group, or multiple groups, are covalently attached to the target protein, thereby initiating the degradation of that protein.

proteasome-mediated ubiquitin-dependent protein catabolic process

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 ubiquitin, and mediated by the proteasome.

cell division

The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.

GO:0051436

negative regulation of ubiquitin-protein ligase activity involved in mitotic cell cycle

Any process that stops, prevents, or reduces the frequency, rate or extent of ubiquitin ligase activity that contributes to the mitotic cell cycle.

TAS

BP

GO:0051437

positive regulation of ubiquitin-protein ligase activity involved in regulation of mitotic cell cycle transition

Any process that activates, maintains or increases the rate of ubiquitin ligase activity that contributes to the regulation of the mitotic cell cycle phase transition.

TAS

BP

GO:0051439

regulation of ubiquitin-protein ligase activity involved in mitotic cell cycle

A cell cycle process that modulates the frequency, rate or extent of ubiquitin ligase activity that contributes to the mitotic cell cycle.

GO:0070979

protein K11-linked ubiquitination

A protein ubiquitination process in which ubiquitin monomers are attached to a protein, and then ubiquitin polymers are formed by linkages between lysine residues at position 11 of the ubiquitin monomers. K11-linked polyubiquitination targets the substrate protein for degradation. The anaphase-promoting complex promotes the degradation of mitotic regulators by assembling K11-linked polyubiquitin chains.

nucleus

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

nucleoplasm

That part of the nuclear content other than the chromosomes or the nucleolus.

TAS

CC

GO:0005680

anaphase-promoting complex

A ubiquitin ligase complex that degrades mitotic cyclins and anaphase inhibitory protein, thereby triggering sister chromatid separation and exit from mitosis. Substrate recognition by APC occurs through degradation signals, the most common of which is termed the Dbox degradation motif, originally discovered in cyclin B.

cytosol

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

protein phosphatase binding

Interacting selectively and non-covalently with any protein phosphatase.
