TGN
Noun
Meaning
TGN (plural TGNs)
Initialism of trans-Golgi network.
Examples
About 5–10 min after its assembly in the endoplasmic reticulum, proinsulin is transported to the trans-Golgi network (TGN) where immature granules are formed.
Once matured, the TGN cisternae dissolves to become secretory vesicles.
Model 2: Cisternal progression/maturation * In this model, the fusion of COPII vesicles from the ER begins the formation of the first cis- cisterna of the Golgi stack, which progresses later to become mature TGN cisternae.
Sulfation of tyrosines and carbohydrates occurs within the TGN.
Transport to the TGN may take about 30 min.
