Gnai1 Gene Summary [Rat]
Enables several functions, including GTPase activating protein binding activity; guanyl ribonucleotide binding activity; and magnesium ion binding activity. Involved in several processes, including cellular response to forskolin; negative regulation of synaptic transmission; and neurotransmitter receptor localization to postsynaptic specialization membrane. Located in centrosome; cytoplasm; and plasma membrane. Part of protein-containing complex. Is active in glutamatergic synapse and postsynapse. Orthologous to human GNAI1 (G protein subunit alpha i1).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Gnai1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
