Breakthrough: Sensors monitor cells at work
Date:7/2/2013

ium becomes toxic. Therefore, its concentration must be very carefully regulated. The transporter for ammonium is conserved in plants, fungi, and, bacteria. It is also present in humans, where it is generally known as the Rhesus factor and plays an important role in kidney function and male fertility.

The team's approach has provided new insights into how the plant ammonium transporter works. And their sensor concept is expected to find many other applications to monitor other types of transporters and transporters in other organisms outside of the plant kingdom and even enzymes.

"For example, in humans such sensors could be used to help understand neurotransmitter transport in the brain or identify new drugs targets," Frommer said.
