Nucleolar localization signals of LIM kinase 2 function as a cell-penetrating peptide.

Abstract

LIM Kinase 2 (LIMK2) is a LIM domain-containing protein kinase which regulates actin polymerization thorough phosphorylation of the actin depolymerizing factor cofilin. It is also known to function as a shuttle between the cytoplasm and nucleus in endothelial cells. A basic amino acid-rich motif in LIMK2 was previously identified to be responsible for this… (More)
