Abstract:
:The human neuroblastoma SH-SY5Y was found to express annexins I, II, IV, V, and VI by western blot analysis. Calcium-dependent membrane-binding proteins were isolated from SH-SY5Y and analysed by 2-dimensional gel electrophoresis. Proteins with Mr and Pi values similar to those of annexins I, II, III, IV, V, and VI were observed. The identity of annexins II and V was confirmed by western blotting. The membrane association of annexins II and V was studied in cells that had been stimulated to release noradrenaline by K+ depolarisation or by treatment with the ionophore A23187. Annexins II and V were both found to associate with membranes in a manner that was resistant to elution with EGTA and required Triton X-100 for their solubilisation. Homogenisation of cells in calcium-containing buffers also resulted in the formation of EGTA-resistant membrane-associated annexins II and V. The results demonstrate calcium-dependent relocation of annexins II and V to membranes in intact cells and suggest that these annexins bind in a calcium-dependent manner to non-phospholipid components of SH-SY5Y membranes. Examination of cells by immunofluorescence microscopy demonstrated that annexin II was homogeneously associated with the plasma membrane before treatment with ionophore and relocated to discrete patches of staining after treatment. Annexin V was found by immunofluorescence to be present in the cytoplasm and in the nucleus, Stimulation of the cells produced no change in the cytoplasmic staining pattern but resulted in a partial relocation of nuclear annexin V to the periphery of the nucleus. The results argue for a general role for both annexins in calcium signalling at discrete intracellular locations. The results are not consistent with the specific involvement proposed previously for annexin II in membrane fusion at sites of vesicle exocytosis.
