Bursts of waves drive immune system 'soldiers' toward invaders
... waves of Hem-1 control the pattern of assembly of building blocks of a second protein, actin. This protein physically contacts the cell membrane and prods it forward. But actin is not only an output of Hem-1 action; it also appears to eliminate the Hem-1 that has assembled it, the new research shows. The sci...UK scientists working to help cut ID theft
