UniProt Annotation
Function Acts as guanine nucleotide exchange factor (GEF) for CDC42. Promotes formation of GPHN clusters. {ECO:0000269PubMed:10559246}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:10559246}.
Disease Associations Epileptic encephalopathy, early infantile, 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. {ECO:0000269PubMed:15215304}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Detected in brain. Detected at low levels in heart. {ECO:0000269PubMed:10559246}.
