RGS Expression Level Precisely Regulates the Duration of Rod Photoresponses

Regulators of G protein signaling (RGS) constitute a family of proteins that bind specifically to the activated α subunits of G proteins (Gα-GTP), acting as GTPase activating proteins, or GAPs, for the rate of GTP hydrolysis. In this issue of Neuron, Krispel et al. resolve a long-standing puzzle in phototransduction, establishing that RGS9 "GAPping" of Gtα-GTP is the molecular mechanism underlying the dominant recovery time constant of mouse rod photoreceptors and that a precise level of expression of RGS9 is required for normal photoresponse timing.
