Protein Vesicular Transport: Targeting Tags

CELLS-NSGJSO

Tags are a critically important component of endomembrane trafficking and targeting.

How are KDEL tags similar to mannose-6-phosphate tags?

A

They are added to proteins in the Golgi network.

B

They are removed from proteins once the proteins get to their proper destinations.

C

They bind to specific receptors, which then target them to specific intracellular compartments.

D

They are amino acid sequences that cells use to sort proteins to specific intracellular compartments.
