From NCBI Gene:
The protein encoded by this gene is a guanine nucleotide exchange factor (GEF) that plays a role in axon formation and neuronal polarization. The encoded protein displays GEF activity toward RAC1 and RAC3 Rho small GTPases but not toward CDC42. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]
Functions as a guanine nucleotide exchange factor (GEF), which activates Rac1 and Rac3 Rho small GTPases by exchanging bound GDP for free GTP. Does not have a GEF activity for CDC42. Required for STMN1 'Ser-15' phosphorylation during axon formation and consequently for neuronal polarization (PubMed:16982419). Has a role in pigmentation (By similarity). Involved in the regulation of cortical neurogenesis through the control of radial glial cells (RGCs) proliferation versus differentiation; negatively regulates the basal-to-apical interkinetic nuclear migration of RGCs by antagonizing the microtubule growth-promoting function of TACC3.

- Epileptic encephalopathy, early infantile, 23
Epileptic encephalopathy, early infantile, 23 (EIEE23): A severe disease characterized by early-onset intractable epilepsy, dysmorphic features, intellectual disability, and cortical blindness. Brain imaging shows an abnormally marked pontobulbar sulcus with mild pontine hypoplasia, white matter abnormalities, and atrophy in the occipital lobe. [MIM:615859]
