Biosensor measures signaling molecules within cilia

Scientists of the Research Center caesar in Bonn, an Institute of the Max Planck Society, developed a new biosensor, which allows to measure nanomolar levels of the second messenger cAMP. The sensor makes it possible to study cAMP signaling with high precision, even in subcellular compartments. Using this new biosensor, the scientists of the Minerva Max Planck Research Group “Molecular Physiology“ headed by Dagmar Wachten and of the Department “Molecular Sensory Systems” headed by Benjamin Kaupp revealed how the production of cAMP is regulated in the flagella of sperm cells from mice.
