  • Function

    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. 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.
  • Tissue specificity

    Highly expressed in brain specifically in caudate nucleus and to a lower extent in amygdala and hippocampus. Also detected in lung.
  • Sequence similarities

    Contains 1 DH (DBL-homology) domain.
    Contains 1 PH domain.
    Contains 1 SH3 domain.
  • Domain

    The DH domain and the PH domain are both required to mediate interaction with EPHA4.
  • Post-translational

    Src-dependent phosphorylation at Tyr-179 upon EPHA4 activation increases the guanine exchange factor activity toward RHOA.
  • Cellular localization

    Cytoplasm. Membrane. Cell projection > growth cone. Associated with membranes. Localizes to axonal growth cones.
