Comments

Comment type	Description
Alternative Products	Event=Alternative splicing; Named isoforms=2; Comment=Additional isoforms seem to exist.; Name=D; Synonyms=F; IsoId=P23625-1; Sequence=Displayed; Name=A; Synonyms=B, C, E, G, H; IsoId=P23625-2; Sequence=VSP_001835, VSP_001836;
Function	Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Could be the transducin analog, an amplifier and one of the transducers of a visual impulse that performs the coupling between opsin and cGMP-phosphodiesterase. Could mediate a subset of olfactory and gustatory responses. {ECO:0000269\|PubMed:2125225, ECO:0000269\|PubMed:8524786}.
Similarity	Belongs to the G-alpha family. G(q) subfamily. {ECO:0000305}.
Tissue Specificity	Isoform D is expressed only in the retina and ocellus of the adult head. Isoform A is expressed in chemosensory cells of the olfactory and taste structures, including a subset of olfactory and gustatory neurons, and in cells of the central nervous system, including neurons in the lamina ganglionaris. {ECO:0000269\|PubMed:2125225, ECO:0000269\|PubMed:8524786}.
