Signaling by transmembrane proteins shifts gears.
The HAMP domain is present in a large number of transmembrane proteins in prokaryotes including histidine kinases, adenylyl cyclases, chemotaxis receptors, and phosphatases. In this issue of Cell, report the NMR structure of a HAMP domain and present data suggesting that it transduces signals through a simple rotation of its four-helix parallel coiled coil.[1]References
