The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.

The removal of tubulin heterodimers from one or both ends of a microtubule.

The cell cycle process in which the controlled breakdown of the nuclear envelope during mitotic cell division occurs.

A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.

The entirety of a process in which information is transmitted within a biological system. This process begins with an active signal and ends when a cellular response has been triggered.

Any process that activates or increases the frequency, rate or extent of ARF protein signal transduction.

Any process that modulates the frequency, rate or extent of the separation of duplicated centrosome components at the beginning of mitosis.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an axon injury stimulus.

Any process that stops, prevents, or reduces the frequency, rate or extent of axon regeneration.

Any process that stops, prevents, or reduces the frequency, rate or extent of axon extension involved in regeneration.

The process in which a cell switches from monopolar cell growth to bipolar cell growth.

Any process that modulates the frequency, rate or extent of the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising microtubules and their associated proteins.

Any process that stops, prevents or reduces the frequency, rate or extent of mitotic spindle elongation.

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.

The lipid bilayer surrounding any of the compartments of the Golgi apparatus.

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

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

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.

The portion of the plasma membrane surrounding a ruffle.

The portion of the plasma membrane surrounding a ruffle.

The portion of the plasma membrane surrounding a ruffle.

The end of a microtubule that does not preferentially grow (polymerize).

The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.
