NGEF / EPHEXIN

Neuronal Guanine Nucleotide Exchange Factor

Acts as a guanine nucleotide exchange factor (GEF) which differentially activates the GTPases RHOA, RAC1 and CDC42. Plays a role in axon guidance regulating ephrin-induced growth cone collapse and dendritic spine morphogenesis. Upon activation by ephrin through EPHA4, the GEF activity switches toward RHOA resulting in its activation. Activated RHOA promotes cone retraction at the expense of RAC1- and CDC42-stimulated growth cone extension.

Gene Name: Neuronal Guanine Nucleotide Exchange Factor
Synonyms: NGEF, ARHGEF27, Ephexin-1, EPHEXIN
Target Sequences: AJ238899 CAC00686.1 Q8N5V2
