Cell biology: Border crossing
James U. Bowie1
Abstract
The 'translocon' complex, which determines whether a protein segment will be inserted into or pushed through the cell membrane, seems to make the decision by performing a thermodynamic measurement.
Cells have a border security system that would put any nation to shame. They need to decide millions of times every nanosecond whether to allow something in or out, and a mistake could mean death.
