Abstract

Cyclin-dependent kinase 5 (Cdk5) is a nontraditional Cdk that is primarily active in postmitotic neurons. An important core function of Cdk5 involves regulating the migration and maturation of embryonic post-mitotic neurons. These developmental roles are dependent on its kinase activity. Initially, there was little evidence indicating a role for Cdk5 in normal cell cycle regulation. Recent data from our lab, however, suggest that Cdk5 plays a crucial role as a cell cycle suppressor in normal post-mitotic neurons and neuronal cell lines. It performs this foundation in a kinase independent manner. Cdk5 normally found in both nucleus and cytoplasm, but it exits the nucleus in neurons risk to death in an AD patient's brain. The shift in sub-cellular location is accompanied by cell cycle re-entry and neuronal death. This "new" function of Cdk5 raises cautions in the design of Cdk5-directed drugs for the therapy of neurodegenerative diseases.

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.
