platelet degranulation

The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet.

GO:0006508

proteolysis

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

IEA

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.

BP

GO:0007596

blood coagulation

The sequential process in which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers.

GO:0008015

blood circulation

The flow of blood through the body of an animal, enabling the transport of nutrients to the tissues and the removal of waste products.

IEA

BP

GO:0030168

platelet activation

A series of progressive, overlapping events triggered by exposure of the platelets to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable hemostatic plug.

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 membrane

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

IEA

CC

GO:0005576

extracellular region

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

extracellular space

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

endoplasmic reticulum lumen

The volume enclosed by the membranes of the endoplasmic reticulum.

TAS

CC

GO:0005886

plasma membrane

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

membrane

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

GO:0030134

ER to Golgi transport vesicle

A vesicle that mediates transport from the endoplasmic reticulum to the Golgi complex; bears a coat formed of the COPII coat complex proteins; such vesicles found associated with endoplasmic reticulum (ER) membranes at steady state, and are involved in ER to Golgi (anterograde) vesicle transport.

serine-type endopeptidase activity

Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).
