Trio Gene Summary [Rat]
Enables enzyme binding activity. Involved in modulation of chemical synaptic transmission. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynapse. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 44 and autosomal dominant intellectual developmental disorder 63 with macrocephaly. Orthologous to human TRIO (trio Rho guanine nucleotide exchange factor). [provided by Alliance of Genome Resources, Jul 2025]

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 Trio often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
