CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC as modulators or transducers in various transmembrane signaling
CC systems. Promotes transcription of 3',5'-cyclic phosphodiesterases pde-
CC 1 and pde-5, leading to reduced cGMP levels in sensory neurons. This
CC causes suppression of insulin production and signaling which leads to
CC increased daf-16 activity and contributes to increased adult lifespan
CC and resistance to oxidative stress. In addition, by reducing cGMP
CC levels, inhibits TGF-beta signaling pathways. Involved in behavioral
CC response to P.aeruginosa by controlling the expression of daf-7, a
CC member of the TGF-beta family, in ASJ sensory neurons.
CC {ECO:0000250|UniProtKB:P28052}.
CC -!- SUBUNIT: G proteins are composed of 3 units; alpha, beta and gamma. The
CC alpha chain contains the guanine nucleotide binding site.
CC -!- SIMILARITY: Belongs to the G-alpha family. G(q) subfamily.
CC {ECO:0000305}.
