Neuronal position in the developing brain is regulated by mouse disabled-1

Abstract

During mammalian brain development, immature neurons migrate radially from the neuroectoderm to defined locations, giving rise to characteristic cell layers. Here we show that targeted disruption of the mouse disabled1 (mdab1) gene disturbs neuronal layering in the cerebral cortex, hippocampus and cerebellum. The gene encodes a cytoplasmic protein, mDab1 p80, which is expressed and tyrosine-phosphorylated in the developing nervous system. It is likely to be an adaptor protein, docking to others through its phosphotyrosine residues and protein-interacting domain. The mdab1 mutant phenotype is very similar to that of the reeler mouse. The product of the reeler gene, Reelin, is a secreted protein that has been proposed to act as an extracellular signpost for migrating neurons. Because mDab1 is expressed in wild-type cortical neurons, and Reelin expression is normal in mdab1 mutants, mDab1 may be part of a Reelin-regulated or parallel pathway that controls the final positioning of neurons.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
