Web8 Nov 2013 · Palade understood implicitly that the ER, Golgi, secretory granules, and plasma membrane had to be interconnected by a series of vesicular carriers that carried cargo from one station to the next—dissociative transport. He also appreciated that the process had to be regulated if compartment specificity was to be maintained. Web4 Apr 2024 · As a readout for PI4K2A-dependent secretory vesicle biogenesis, we quantified SPP1-containing vesicle numbers in the cytoplasm and found that MYOIIA depletion reduced the numbers of SPP1-containing vesicles per cell similarly to PI4K2A depletion (Figure 5, G and H, and Supplemental Figure 7B), supporting a role for MYOIIA in PI4K2A-dependent ...
