CC   -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC       as a modulator or transducer in various transmembrane signaling
CC       systems. This major G-protein of the squid photoreceptor is involved in
CC       visual transduction. The beta and gamma chains are required for the
CC       GTPase activity, for replacement of GDP by GTP, and for G protein-
CC       effector interaction (By similarity). Required for normal chemotaxis in
CC       response to cAMP. {ECO:0000250, ECO:0000269|PubMed:11598203}.
CC   -!- SUBUNIT: G proteins are composed of 3 units, alpha, beta and gamma.
CC       Interacts with gpbA, and this requires phlp1.
CC       {ECO:0000269|PubMed:16135826}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305|PubMed:14517243,
CC       ECO:0000305|PubMed:16135826}; Lipid-anchor
CC       {ECO:0000305|PubMed:14517243, ECO:0000305|PubMed:16135826}; Cytoplasmic
CC       side {ECO:0000305|PubMed:14517243, ECO:0000305|PubMed:16135826}.
CC   -!- DEVELOPMENTAL STAGE: Expressed in vegetative cells. Expression rises
CC       within 6 hours after the initiation of development and gradually
CC       decreases following the mound stage. {ECO:0000269|PubMed:11598203}.
CC   -!- PTM: This protein is thought to be subject to lipidation, and this
CC       requires phlp1. {ECO:0000269|PubMed:16135826}.
CC   -!- SIMILARITY: Belongs to the G protein gamma family. {ECO:0000305}.
