The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.

The directed movement of substances within the Golgi, mediated by small transport vesicles. These either fuse with the cis-Golgi or with each other to form the membrane stacks known as the cis-Golgi reticulum (network).

Any process that modulates the rate of GTP hydrolysis by a GTPase.

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.

Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.

The controlled shedding of floral organs.

Any process that stops, prevents, or reduces the frequency, rate, extent or direction of cell growth.

Formation of a macromolecular complex between the cytoplasmic coat proteins on clathrin-coated vesicles and proteins and/or lipoproteins that are going to be transported by a vesicle.

Any process that activates or increases the frequency, rate or extent of erythrocyte differentiation.

Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.

The directed movement of substances within a cell by a cellular process that begins with the formation of membrane-bounded vesicles in which the transported substances are enclosed or located in the vesicle membrane which are then targeted to, and fuse with, an acceptor membrane contributing to the shedding of a floral organ.

The controlled shedding of a leaf.

Any process that initiates the activity of an inactive GTPase through the replacement of GDP by GTP.

Any process that modulates the frequency, rate or extent of retrograde transport, endosome to Golgi.

Any process that modulates the frequency, rate or extent of clathrin-mediated endocytosis.

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

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

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

A vacuole to which materials ingested by endocytosis are delivered.

The network of interconnected tubular and cisternal structures located within the Golgi apparatus on the side distal to the endoplasmic reticulum, from which secretory vesicles emerge. The trans-Golgi network is important in the later stages of protein secretion where it is thought to play a key role in the sorting and targeting of secreted proteins to the correct destination.

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

A vesicle with a coat formed of clathrin connected to the membrane via one of the clathrin adaptor complexes.

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 region at the end of the longest axis of a cylindrical or elongated cell.
