Apoer2: A Reelin Receptor to Remember
The extracellular protein Reelin is crucial for neuronal positioning during brain development, but its expression persists long after cell migration is completed. In this issue of Neuron, Beffert et al. demonstrate that Reelin exerts an additional function in the mature brain, to modulate synaptic plasticity and to favor memory formation. This activity is carried out exquisitely by the Apoer2 r...
متن کاملApoER2 processing by presenilin-1 modulates reelin expression.
The reelin signaling protein and its downstream components have been associated with synaptic plasticity and neurotransmission. The reelin signaling pathway begins with the binding of reelin to the transmembrane lipoprotein receptor apolipoprotein E receptor 2 (ApoER2), which in turns induces the sequential cleavage of ApoER2 by the sequential action of α- and γ-secretases. Using conditional-kn...
متن کاملSorting Nexin 17 Regulates ApoER2 Recycling and Reelin Signaling
ApoER2 is a member of the low density-lipoprotein receptor (LDL-R) family. As a receptor for reelin, ApoER2 participates in neuronal migration during development as well as synaptic plasticity and survival in the adult brain. A previous yeast two-hybrid screen showed that ApoER2 is a binding partner of sorting nexin 17 (SNX17) - a cytosolic adaptor protein that regulates the trafficking of seve...
متن کاملReelin-dependent ApoER2 downregulation uncouples newborn neurons from progenitor cells
Reelin and its receptor machinery are well known to be required for the migration and positioning of neocortical projection neurons. More recently, reelin has been shown both necessary and sufficient to determine the rate of neocortical neurogenesis. The molecular links underlying its seemingly distinct proliferative and post-proliferative functions remain unknown. Here we reveal an enriched ex...
متن کاملReelin and its receptors, VLDLR and ApoER2, in melanocytic nevi
Reelin is an extracellular signaling protein synthesized by Cajal-Retius cells in utero and early after birth, its presence being signaled in adult life too. Reelin acts on its receptors, VLDLR and ApoER2, acting on cytoskeleton, controlling migration and subsequently positioning and stabilizing the cortical neurons. We investigated the reelin presence and its receptors, VLDLR and ApoER2, in me...
