    basic FUNCTION
  • putative intracellular tyrosine kinase adaptor protein
  • likely involved in brain development
  • activating tyrosine kinases
  • intracellular adaptor that is tyrosine phosphorylated when RELN, a secreted glycoprotein, binds to the lipoprotein receptors VLDLR and ApoER2 on the surface of neurons
  • involved in neuronal migration and lamination in the developing cerebral cortex
  • resides within an unstable common site fragile region and might play a role in tumorigenesis
  • key signaling molecule in the Reelin pathway that plays a critical role in neuronal migration and positioning during brain development 5)
  • is required in radially migrating neurons for glia-independent somal translocation, but not for glia-guided locomotion
  • mediates reelin signalling and plays critical roles in early brain development such as the stereotypical positioning of neurons in the brain
  • may function as a tumor suppressor
  • plays a key role in reelin-mediated neuronal migration during brain development
  • adaptor protein that is an obligate effector of the RELN signaling pathway, and is critical for neuronal migration and dendrite outgrowth during development
  • critical regulator of synaptic function and hippocampal-dependent associative and spatial learning
  • DAB1 functions downstream of reelin action on the homeostasis of the crypt-villus unit
  • possible involvements of RELN and DAB1 in the peripheral migrating stream
  • plays a vital role in cytoskeleton, neuronal migration, and proliferation

    PATHWAY
    metabolism
    signaling
  • important role for RELN-DAB1 signaling in the adult forebrain
  • RELN/DAB1 signaling in the embryonic limb regulates the chondrogenic differentiation of digit mesodermal progenitors
  • RELN-DAB1 signaling pathway regulates development of the mammalian brain, including neuron migrations in various brain regions, as well as learning and memory in adults
  • a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • non receptor tyrosine kinase, VLDLR, APOER2
  • interaction with Src and Crk
  • interacting with CUL5 (plays an essential role in regulating neuron migrations during cortical development, possibly by opposing a promigratory effect of DAB1) (Feng 2007)
  • interacting with FYN (FYN modulation of DAB1 having effects on amyloid precursor protein and LRP8 processing) (Hoe 2008)
  • NOVA2 regulates an RNA switch controlling the ability of DAB1 to mediate neuronal responsiveness to reelin signaling and neuronal migration
  • STK25 regulates neuronal polarization and Golgi morphology in an antagonistic manner to DAB1
  • induction of Disabled-1 (DAB1) tyrosine phosphorylation, and the subsequent activation of Src family kinases, were found to be essential steps for the activation of NOTCH1 signaling by RELN
  • DAB1 suppresses SH3KBP1 phosphorylation at Ser587
  • SH3KBP1 participates in RELN signaling through the binding to DAB1
  • major role of VEGFA in the regulation of RELN signaling, and DAB1 as a key molecule in the cross talk between reelin and VEGFA signaling pathways
  • RELN governs cell migration through activation of multiple intracellular signaling events by means of the receptors LRP8 and VLDLR, and the intracellular adaptor protein Disabled-1 (DAB1)
  • during neuronal migration RELN interacts with PAFAH1B1 and induces nuclear translocation, accompanied by the ubiquitination of phosphorylated DAB1
  • extracellular Reelin binds to cell surface receptors and activates phosphorylation of the intracellular DAB1 protein
  • mediated AGT-induced podocyte apoptosis via MAPK14 signaling pathway
