intracellular protein transport

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.

IMP

BP

GO:0006887

exocytosis

A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle by fusion of the vesicle with the plasma membrane of a cell. This process begins with steps that prepare vesicles for fusion with the membrane (tethering and docking) and ends when vesicle fusion is complete. This is the process in which most molecules are secreted from eukaryotic cells.

GO:0006888

ER to Golgi vesicle-mediated transport

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.

TAS

BP

GO:0006890

retrograde vesicle-mediated transport, Golgi to ER

The directed movement of substances from the Golgi back to the endoplasmic reticulum, mediated by vesicles bearing specific protein coats such as COPI or COG.

TAS

BP

GO:0006891

intra-Golgi vesicle-mediated transport

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).

IBA

BP

GO:0016192

vesicle-mediated transport

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.

regulation of exocytosis

Any process that modulates the frequency, rate or extent of exocytosis.

IMP

GO:0048208

COPII vesicle coating

The addition of COPII proteins and adaptor proteins to ER membranes during the formation of transport vesicles, forming a vesicle coat.

Golgi stack

The set of thin, flattened membrane-bounded compartments, called cisternae, that form the central portion of the Golgi complex. The stack usually comprises cis, medial, and trans cisternae; the cis- and trans-Golgi networks are not considered part of the stack.

IDA

CC

GO:0014069

postsynaptic density

The postsynaptic density is a region that lies adjacent to the cytoplasmic face of the postsynaptic membrane at an excitatory synapse. It forms an electron-dense disc that consists of a range of proteins with different functions, some of which contact the cytoplasmic domains of ion channels in the postsynaptic membrane. The proteins making up the disc include structural proteins linked to the actin cytoskeleton and signalling machinery, such as protein kinases and phosphatases.
