The glycerol channel, too, has three faces, each of which interacts with the glycerol molecule to selectively filter only this molecule into the cell.To pass through the "three-faced" channel, a molecule must also have three aspects: ...Dinosaurs: New study counters age-old theory

...not needed - the key domains of the N-WASP protein physically torque the "working end" of the protein so that it cannot trigger actin polymerization. But when the two signal molecules bind to their separate target domains on the N-WASP protein, their combined effect frees the protein to trigger actin growth. T...... a skeletal protein called actin that piles up and physically propels the newly formed bacteria around the cell.
