GNAO1 (guanine nucleotide-binding protein, alpha-other) gene, located on chromosome 16q12.2, encodes the alpha subunit of the heterotrimeric guanine nucleotide binding proteins (G proteins). Three functional G-protein subtypes are defined, inhibitory G-proteins (Gi), stimulatory G-proteins (Gs), and other (Go). Go proteins modulate neurotransmitter release by mediating the presynaptic auto-inhibitory effect of several neurotransmitters on their receptors. Gαo subunit encoded by GNAO1 is expressed in brain tissue and has an important role in brain function .
