secretory granule

Term Information

Accession
GO:0030141
Name
secretory granule
Ontology
cellular_component
Synonyms
secretory vesicle
Alternate IDs
None
Definition
A small subcellular vesicle, surrounded by a membrane, that is formed from the Golgi apparatus and contains a highly concentrated protein destined for secretion. Secretory granules move towards the periphery of the cell and upon stimulation, their membranes fuse with the cell membrane, and their protein load is exteriorized. Processing of the contained protein may take place in secretory granules. Source: ISBN:0198506732, GOC:mah
Comment
Note that the term 'secretory vesicle' is sometimes used in this sense, but can also mean 'transport vesicle ; GO:0030133'.
