G2/M transition of mitotic cell cycle

The mitotic cell cycle transition by which a cell in G2 commits to M phase. The process begins when the kinase activity of M cyclin/CDK complex reaches a threshold high enough for the cell cycle to proceed. This is accomplished by activating a positive feedback loop that results in the accumulation of unphosphorylated and active M cyclin/CDK complex.

GO:0007051

spindle organization

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the spindle, the array of microtubules and associated molecules that forms between opposite poles of a eukaryotic cell during DNA segregation and serves to move the duplicated chromosomes apart.

IMP

BP

GO:0007062

sister chromatid cohesion

The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.

TAS

BP

GO:0007067

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.

IEA

BP

GO:0030951

establishment or maintenance of microtubule cytoskeleton polarity

Any cellular process that results in the specification, formation or maintenance of polarized microtubule-based cytoskeletal structures.

IMP

BP

GO:0050658

RNA transport

The directed movement of RNA, ribonucleic acids, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

ISS

BP

GO:0051297

centrosome organization

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized.

IMP

BP

GO:0051301

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.

IEA

BP

GO:0098609

cell-cell adhesion

The attachment of one cell to another cell via adhesion molecules.

IEA

CC

GO:0000776

kinetochore

A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.

IDA

CC

GO:0000922

spindle pole

Either of the ends of a spindle, where spindle microtubules are organized; usually contains a microtubule organizing center and accessory molecules, spindle microtubules and astral microtubules.

IDA

CC

GO:0000930

gamma-tubulin complex

A multiprotein complex composed of gamma-tubulin and other non-tubulin proteins. Gamma-tubulin complexes are localized to microtubule organizing centers, and play an important role in the nucleation of microtubules. The number and complexity of non-tubulin proteins associated with these complexes varies between species.

IDA

CC

GO:0005813

centrosome

A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.

IDA

CC

GO:0005829

cytosol

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

TAS

CC

GO:0005913

cell-cell adherens junction

An adherens junction which connects a cell to another cell.

IDA

CC

GO:0015630

microtubule cytoskeleton

The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.

ISS

CC

GO:0016020

membrane

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

IDA

CC

GO:0035371

microtubule plus-end

The growing (plus) end of a microtubule. In vitro, microtubules polymerize more quickly at the plus end than at the minus end. In vivo, microtubule growth occurs only at the plus end, and the plus end switches between periods of growth and shortening, a behavior known as dynamic instability.

IDA

CC

GO:0043234

protein complex

A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.

IDA

MF

GO:0005515

protein binding

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

IPI

MF

GO:0098641

cadherin binding involved in cell-cell adhesion

Any cadherin binding that occurs as part of the process of cell-cell adhesion.
