    ..These results demonstrate the importance of PDZ-dependent reverse signaling for a subset of Ephrin-B1 developmental roles in vivo. ..

    ..We therefore examined whether the EphB2 receptor tyrosine kinase could directly effect proliferation of SVZ neural precursors and/or direct the cell fate of ..

    ..These results indicate an important role for GRIP1 in dendrite morphogenesis by serving as an adaptor protein for kinesin-dependent transport of EphB receptors to dendrites. ..

    ..The reduced proliferation was not the result of abnormal vascular development within the palate. In conclusion, strong evidence is provided for specific and co-operative roles of EphB2 and EphB3 in palate development. ..
