Gdi1 - GDP dissociation inhibitor 1

Enables Rab GDP-dissociation inhibitor activity and small GTPase binding activity. Involved in negative regulation of axonogenesis; positive regulation of axon extension; and response to calcium ion. Located in axon; myelin sheath; and neuronal cell body. Part of protein-containing complex. 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 2022]
