Guanine nucleotide-binding protein G(olf) subunit alpha is a protein that in humans is encoded by the GNAL gene. Its main product is the heterotrimeric G-protein alpha subunit Golf-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.

Second messenger system

Second messengers are intracellular signaling molecules released by the target cell in response to exposure to extracellular signaling molecules, the first messengers. Second messengers trigger physiological changes at cellular level such as proliferation, differentiation, migration, survival, apoptosis and depolarization.

G protein-coupled receptor

G protein-coupled receptors, also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large group of evolutionarily related proteins that are cell surface receptors that detect molecules outside the cell and activate cellular responses. They are coupled with G proteins.

Heterotrimeric G protein

Heterotrimeric G protein, also sometimes referred to as the "large" G proteins are membrane-associated G proteins that form a heterotrimeric complex. The biggest non-structural difference between heterotrimeric and monomeric G protein is that heterotrimeric proteins bind to their cell-surface receptors, called G protein-coupled receptors (GPCR), directly.
