Abstract:
:We have studied the convergence of the biosynthetic lysosomal route marked by the newly synthesized lysosomal enzyme arylsulfatase A (ASA) with the endosomal/prelysosomal compartment in ASA overexpressing baby hamster kidney (BHK) cells. A monoclonal antibody against ASA conjugated to transferrin (Tf-alpha ASA) was used to load the endocytic pathway via the transferrin receptor. Subsequent internalization of [125I]labeled ASA and Tf-alpha ASA conjugates at 18 degrees C followed by rewarming to 37 degrees C showed that immunocomplexes were formed within the recycling pathway and released into the medium. Furthermore, in cells labeled with [35S]methionine for 10 min about 54% of newly synthesized ASA passed into Tf-alpha ASA accessible compartments during a 4 hour chase period and accumulated in the medium. These data indicate that in overexpressing BHK cells the majority of newly synthesized ASA is transported to the lysosome via transferrin receptor-containing early endosomes.
