A cell cycle process that sets the alignment of mitotic spindle relative to other cellular structures.

A microtubule-based process that results in the movement of organelles, other microtubules, or other cellular components. Examples include motor-driven movement along microtubules and movement driven by polymerization or depolymerization of microtubules.

The directed movement of the nucleus.

Separation of duplicated centrosome components at the beginning of mitosis. The centriole pair within each centrosome becomes part of a separate microtubule organizing center that nucleates a radial array of microtubules called an aster. The two asters move to opposite sides of the nucleus to form the two poles of the mitotic spindle.

The process whose specific outcome is the progression of an embryo over time, from zygote formation until the end of the embryonic life stage. The end of the embryonic life stage is organism-specific and may be somewhat arbitrary; for mammals it is usually considered to be birth, for insects the hatching of the first instar larva from the eggshell.

The directed movement of the male and female pronuclei towards each other prior to their fusion.

Self-propelled movement of a cell or organism from one location to another.

The removal of the apoptotic cell by phagocytosis, by a neighboring cell or by a phagocyte.

The formation of spores derived from the products of meiosis. A cellular spore is a cell form that can be used for dissemination, for survival of adverse conditions because of its heat and dessication resistance, and/or for reproduction.

The process of producing non-motile spores, called conidia, via mitotic asexual reproduction in higher fungi. Conidia are haploid cells genetically identical to their haploid parent. They are produced by conversion of hyphal elements, or are borne on sporogenous cells on or within specialized structures termed conidiophores, and participate in dispersal of the fungus.

The directed movement of synaptic vesicles.

The cell cycle process in which a connection between chromatids assembles, indicating where an exchange of homologous segments has taken place by the crossing-over of non-sister chromatids.

The aggregation, arrangement and bonding together of a set of components to form the spindle, the array of microtubules and associated molecules that serves to move duplicated chromosomes apart.

Any process in which a centrosome is maintained in a specific location within a cell and prevented from moving elsewhere.

The process of communication from a neuron to another neuron across a synapse using the neurotransmitter gamma-aminobutyric acid (GABA).

The process of communication from a neuron to another neuron across a synapse using the neurotransmitter gamma-aminobutyric acid (GABA).

Any process that modulates the frequency, rate or extent of microtubule motor activity.

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

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The microtubule organizing center in fungi; functionally homologous to the animal cell centrosome.

An array of microtubules emanating from a spindle pole MTOC that do not connect to kinetochores.

Any dynein complex with a homodimeric dynein heavy chain core that catalyzes movement along a microtubule. Cytoplasmic dynein complexes participate in many cytoplasmic transport activities in eukaryotes, such as mRNA localization, intermediate filament transport, nuclear envelope breakdown, apoptosis, transport of centrosomal proteins, mitotic spindle assembly, virus transport, kinetochore functions, and movement of signaling and spindle checkpoint proteins. Some complexes participate in intraflagellar transport. Subunits associated with the dynein heavy chain mediate association between dynein heavy chain and cargoes, and may include light chains and light intermediate chains.

Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle.

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.

Cytoplasm situated near, or occurring around, the nucleus.
