The disabled 1 (Dab1) p80 protein is essential for reelin signaling during brain development. p80 has an N-terminal domain for association with reelin receptors, followed by reelin-dependent tyrosine phosphorylation sites and about 310 C-terminal residues of unknown function. We have generated mutant mice that express only a natural splice form of Dab1, p45, that lacks the C-terminal region of ...
Reelin is an extracellular protein that directs the organization of cortical structures of the brain through the activation of two receptors, the very low-density lipoprotein receptor (VLDLR) and the apolipoprotein E receptor 2 (ApoER2), and the phosphorylation of Disabled-1 (Dab1). Lis1, the product of the Pafah1b1 gene, is a component of the brain platelet-activating factor acetylhydrolase 1b...
Apolipoprotein E receptor 2 (Apoer2), a member of the LDL receptor gene family, and its ligand Reelin control neuronal migration during brain development. Apoer2 is also essential for induction of long-term potentiation (LTP) in the adult brain. Here we show that Apoer2 is present in the postsynaptic densities of excitatory synapses where it forms a functional complex with NMDA receptors. Reeli...
Reelin is an extracellular matrix neuroprotein which plays important roles during development and maturation of cerebellum. In the postnatal cerebellum, Reelin is synthesized by cerebellar granule cells and secreted to extracellular matrix. This secreted protein modulates adult synaptic function, neurotransmitter release and regulates plasticity. Exercise has beneficial effects on central nervo...
The mouse reelin gene (Reln) encodes a novel protein that, when mutated, results in the characteristic reeler phenotype. A key component of this phenotype is the extensive disruption of the organization of many brain structures. Reelin is believed to be an extracellular protein that controls neural cell positioning during brain development. The reelin gene is conserved in many vertebrate specie...
The real role of reelin ttractants and repellents shunt neurons into their correct final location. But now Iris Hack, Harold Cremer (Université Mediterranée, Marseille, France), and colleagues have found evidence that reelin fits into neither of these categories. They propose, instead, that reelin converts cells that are migrating in association with each other into individual cells that can st...

An early and fundamental step of the laminar organization of developing neocortex is controlled by the developmental programs that critically depend on the activities of reelin-positive cells in the marginal zone. However, the ontogeny of reelin-positive cells remained elusive. To gain insights into the spatial and temporal regulation of reelin-positive marginal zone cell development, we used a...
Reelin regulates nervous system development and modulates synaptic plasticity in the adult brain. Several findings suggest that alterations in Reelin signaling may contribute to neuronal dysfunction associated with Alzheimer’s disease (AD). Cell surface receptors for Reelin, including integrins and very-low-density lipoprotein receptor/apolipoprotein E2 receptor, may be targets of amyloid(A ) p...
Reelin regulates telencephalic and cerebellar lamination during mammalian development and is expressed in several structures of the adult brain; however, only traces of reelin were believed to be in peripheral tissues. Because reelin structurally resembles extracellular matrix proteins, and because many of these proteins are expressed in blood, we hypothesized that reelin also might be detectab...
