LIM kinase 1 (LIMK1) is a unique dual specificity serine/threonine kinase containing two N-terminal LIM domains in tandem, a PDZ domain and a C-terminal catalytic domain. LIMK1 is involved in modulation of actin cytoskeleton through inactivating phosphorylation of the ADF (actin depolymerization factor) family protein cofilin. Recent studies have shown that LIMK1 is upregulated in breast and prostate cancer cells and tissues, promotes metastasis in animals and induces acquisition of an invasive phenotype when ectopically expressed in benign prostate epithelial (BPH) cells. Furthermore, overexpression of LIMK1 was associated with altered sub cellular localization of the membrane type 1 matrix metalloprotease …
