Arhgef9 Gene Summary [Mouse]
Predicted to enable guanyl-nucleotide exchange factor activity. Involved in regulation of postsynaptic specialization assembly. Located in postsynaptic density. Is active in GABA-ergic synapse. Is expressed in several structures, including central nervous system; dorsal root ganglion; and ear. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 8. Orthologous to human ARHGEF9 (Cdc42 guanine nucleotide exchange factor 9). [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 mouse Arhgef9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
