CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC as modulators or transducers in various transmembrane signaling
CC systems. Involved in behavioral responses to P.aeruginosa by
CC controlling the expression of daf-7, a member of the TGF-beta family,
CC in ASJ sensory neurons (PubMed:25303524).
CC {ECO:0000269|PubMed:25303524}.
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}.
