title: The Reelin signaling pathway in mouse cortical development.
abstract: Most of the cerebral cortex derives from the cortical plate which, in all mammals, is radially organized and develops from inside to outside. Several genes involved in the organization and inside-outside development of the embryonic cortical plate in the mouse form the so-called Reelin signaling pathway. Biochemical and genetic arguments show that the extracellular matrix protein Reelin binds to two lipoprotein receptors (VLDLR and ApoER2), which relay the Reelin signal inside target neurons by docking the tyrosine kinase adapter disabled-1 (Dab1). In addition, biochemical evidence suggests that the integrins alpha 3/beta 1 and protocadherins of the CNR family may also modulate the Reelin signal. The mechanisms by which the presence of Reelin stops migration and instructs the radial organization of cortical plate cells remains unknown.
