The directed movement of a protein from the nucleus into the cytoplasm.

Any process that stops, prevents, or reduces the frequency, rate or extent of microtubule depolymerization; prevention of depolymerization of a microtubule can result from binding by 'capping' at the plus end (e.g. by interaction with another cellular protein of structure) or by exposing microtubules to a stabilizing drug such as taxol.

The cell cycle process in which centrosome duplication and separation takes place. The centrosome cycle can operate with a considerable degree of independence from other processes of the cell cycle.

The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster.

The orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster.

Any cellular process that results in the specification, formation or maintenance of a polarized follicular epithelial sheet.

The process in which one or more ubiquitin groups are added to a protein.

Creation of the central hole of a tube in an open tracheal system through which gases flow.

The process whose specific outcome is the progression of a trachea over time, from its formation to the mature structure. The trachea is the portion of the airway that attaches to the bronchi as it branches.

The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of mitosis.

Any process that modulates the frequency, rate or extent of cellular response to hypoxia.

A protein complex that possesses ubiquitin ligase activity; the complex is usually pentameric; for example, in mammals the subunits are pVHL, elongin B, elongin C, cullin-2 (Cul2), and Rbx1.
