In vertebrate photoreceptor cells, rapid recovery from light excitation is dependent on the RGS9⋅Gβ5 GTPase-activating complex located in the light-sensitive outer segment organelle. RGS9⋅Gβ5 is tethered to the outer segment membranes by its membrane anchor, R9AP. Recent studies indicated that RGS9⋅Gβ5 possesses targeting information that excludes it from(More)
The members of the R7 regulator of G-protein signaling (RGS) protein subfamily are versatile regulators of G-protein signaling throughout the nervous system. Recent studies indicate that they are often found in complexes with membrane anchor proteins that serve as versatile modulators of their activity, intracellular targeting, and stability.
