| Outline of Final Research Achievements |
Cells change their morphology in response to the outer stimuli. SWAP-70 has been known to play an important role in the regulation of cell shape change through the binding to both of the cell membrane and actin cytoskeleton. In this study, we show that SWAP-70 oligomerizes prior to actin polymerization in response to growth factor stimulation. The binding to activated Rac was shown to be required for the oligomerization of SWAP-70 and growth factor-induced cell shape change, suggesting the contribution of oligomerization of SWAP-70 to the stimulus-dependent cell shape change.
