Gdi1 Gene Summary [Mouse]
Predicted to enable Rab GDP-dissociation inhibitor activity and small GTPase binding activity. Predicted to be involved in several processes, including Rab protein signal transduction; negative regulation of protein targeting to membrane; and regulation of axonogenesis. Located in myelin sheath. Is expressed in several structures, including liver; nervous system; placenta; sensory organ; and spleen. Used to study non-syndromic X-linked intellectual disability. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability; non-syndromic X-linked intellectual disability 41; and psychotic disorder. Orthologous to human GDI1 (GDP dissociation inhibitor 1). [provided by Alliance of Genome Resources, Apr 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 Gdi1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
