Abstract

Dyrk1A and its Drosophila orthologue, the protein minibrain (mnb), belong to a family of serine/threonine kinases involved in the development of the central nervous system (CNS). However, additional roles for Dyrk1A have to be proposed, as its expression is still prominent in the adult brain. To gain insight into Dyrk1A physiological roles we have studied the distribution of this kinase in the CNS of mice in adulthood. A homogeneous diffuse immunostaining of variable intensity was detected throughout the neuropile, with the white matter displaying faint Dyrk1A immunoreactivity. Dyrk1A immunostaining was strong in the olfactory bulb, the cerebellar cortex and functionally related structures, the spinal cord and most of the motor nuclei of the midbrain and brain stem. These data agree with a possible implication of this kinase in the physiology of olfaction and motor functions. Cellular and subcellular localisation of Dyrk1A was also studied in primary cell culture of cerebellum, one of the structures showing significant Dyrk1A immunostaining in the adult. The distribution of Dyrk1A in primary cell culture showed the presence of this protein in the nucleus and the cytoplasm of both neurons and astrocytes. Moreover, studies on the subcellular distribution of Dyrk1A in whole brain homogenates of adult mice showed the presence of this protein both in nuclear and cytoplasm-enriched fractions, thus supporting selective functions of this kinase in these two subcellular compartments.…

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.
