Solution structure of the SH3 domain from Rho guanine nucleotide exchange factor 9

Disease

[ARHG9_HUMAN] Defects in ARHGEF9 are the cause of pileptic encephalopathy, early infantile, type 8 (EIEE8) [MIM:300607]. A disorder characterized by hyperekplexia and early infantile epileptic encephalopathy. Neurologic features include exaggerated startle response, seizures, impaired psychomotor development, and mental retardation. Seizures can be provoked by tactile stimulation or extreme emotion.[1]

Function

[ARHG9_HUMAN] Acts as guanine nucleotide exchange factor (GEF) for CDC42. Promotes formation of GPHN clusters.[2]
