B Golgi apparatus Trans Golgi network TGN is particularly involved in sorting of proteins - Harper 28thf487, 2 7th518Two branches of protein sortingThe rough endoplasmic reticulum branch of protein sortingNewly synthesized proteins are inserted into the ER membraneor lumen from membrane-bound polyribosomes.Proteins then pass through the various subcompartments of the Golgi until they reach the Trans - Golgi Network TGN, the exit side of Golgi..In the TGS, proteins are sorted and seggregated.The Cytosolic branch of protein sorting
