Disease relevance of Dcx

 

High impact information on Dcx

  • Doublecortin maintains bipolar shape and nuclear translocation during migration in the adult forebrain [5].
  • A second locus, doublecortin-like kinase (Dclk), encodes a protein with similar "doublecortin domains" and microtubule stabilization properties that may compensate for Dcx [6].
  • Dcx and Dclk may directly or indirectly regulate microtubule-based vesicle transport, a process critical to both neuronal migration and axon outgrowth [6].
  • Dcx/Dclk-deficient dissociated neurons show abnormal axon outgrowth and dendritic structure, with defects in axonal transport of synaptic vesicle proteins [6].
  • Doublecortin-like kinase controls neurogenesis by regulating mitotic spindles and M phase progression [7].

Associations of Dcx with chemical compounds

  • Early after BrdU, CR colocalized with immature neuronal marker doublecortin; and later with persisting neuronal marker NeuN [15].
  • Ipsilateral GCD progressively developed after KA injection and was paralleled by a gradual decrease in the expression of doublecortin, a marker of newly generated granule cells, in the dentate subgranular layer [16].
  • In vitro assays (using biochemical methods, DIC microscopy and electron microscopy) demonstrate that Doublecortin binds microtubules directly, stabilizes them and causes bundling [17].
  • Therefore, SGZ progenitor cells committed to a neuronal phenotype before KA treatment complete their differentiation despite the rapid down-regulation of doublecortin and PSA-NCAM [18].
  • In addition, blocking endothelial nitric oxide synthase activity (via a daily injection of 20 mg/kg L-nitroimidazole ornithine) during exercise reduced the number of cells within the dentate gyrus that were immunoreactive for Ki-67 protein and doublecortin [19].
 

Regulatory relationships of Dcx

  • The isolated kinase domain retains catalytic activity and is structurally similar to CPG16, a second product of the DCLK gene expressed in the adult brain that lacks the doublecortin domain [20].
