Abstract

PAK4 is the most recently identified member of the PAK family of serine/threonine kinases. PAK4 differs from other members of the PAK family in sequence and in many of its functions. Previously, we have shown that an important function of this kinase is to mediate the induction of filopodia in response to the Rho GTPase Cdc42. Here we show that PAK4 also regulates the activity of the protein kinase LIM kinase 1 (LIMK1). PAK4 was shown to interact specifically with LIMK1 in binding assays. Immune complex kinase assays revealed that both wild-type and constitutively active PAK4 phosphorylated LIMK1 even more strongly than PAK1, and activated PAK4 stimulated LIMK1's ability to phosphorylate cofilin. Immunofluorescence experiments revealed that PAK4 and LIMK1 cooperate to induce cytoskeletal changes in C2C12 cells. Furthermore, dominant negative LIMK1 and a mutant cofilin inhibited the specific cytoskeletal and cell shape changes that were induced in response to a recently characterized constitutively activated PAK4 mutant.

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.
