How does the affinity of M6P receptor proteins for the mannose 6-phosphate marker change between the TGN and early endosome? Which coat protein is mainly responsible for their transport from the TGN to the endosome?
A) The affinity is higher in the TGN; clathrin B) The affinity is higher in the TGN; retromer C) The affinity is higher in endosomes; clathrin D) The affinity is higher in endosomes; retromer
