GNAL

Guanine nucleotide-binding protein G(olf) subunit alpha is a protein that in humans is encoded by the GNAL gene.^[5][6] Its main product is the heterotrimeric G-protein alpha subunit G_olf-α, a member of the Gs alpha subunit family that is a key component of G protein-coupled receptor-regulated adenylyl cyclase signal transduction pathways in the olfactory system and the striatum in the brain. It also mediated D1 receptor signalling in the striatum and is hence involved in motor control.^[7]
