Vesicle Sorting G Proteins and Vesicle Trafficking

Attenuating a cellular signal is just as critical as inducing it. For example, regulator of G protein signaling (RGS) proteins modulate the signaling output from receptor-coupled heterotrimeric G proteins. Zheng et al. (see the Perspective by von Zastrow and Mostov) have identified what has been an elusive RGS for the Gαs class of G proteins. Named RGS-PX1, it also contains a membrane-interacting PhoX domain whose presence suggests a link between G protein signaling and vesicle trafficking in cells.
