Mutations that rescue the paralysis of Caenorhabditis elegans ric-8 (synembryn) mutants activate the G alpha(s) pathway and define a third major branch of the synaptic signaling network.

Abstract excerpt

To identify hypothesized missing components of the synaptic G alpha(o)-G alpha(q) signaling network, which tightly regulates neurotransmitter release, we undertook two large forward genetic screens in the model organism C. elegans and focused first on mutations that strongly rescue the paralysis of ric-8(md303) reduction-of-function mutants, previously shown to be defective in G alpha(q) pathway activation....
