Fig. 7: Proposed working model for EphB6/EphrinB2 gain of function in cortical soma spacing.

Overexpression of EphB6 receptor or EphrinB2 results in soma clumping of cortical neurons, whereas simultaneous overexpression of both eliminates the clumping phenotype. The interaction of extracellular ___domain of EphB6 with EphrinB2, and EphB6 with intracellular ___domain of EphrinB2 are the key components that may restore intracellular signaling pathways that are responsible for soma spacing impaired by overexpression EphB6 or EphrinB2.
