The N-terminal LIM domain negatively regulates the kinase activity of LIM-kinase 1.
LIM-kinase 1 (LIMK1, where LIM is an acronym of the three gene products Lin-11, Isl-1 and Mec-3) is a serine/threonine kinase that phosphorylates cofilin and regulates actin cytoskeletal reorganization. LIMK1 contains two LIM domains and a PDZ (an acronym of the three proteins PSD-95, Dlg and ZO-1) domain in the N-terminal half and a kinase domain in the C-terminal half. In this study we examin...
متن کاملLIM kinase 1 (LIMK1) interacts with tropomyosin-related kinase B (TrkB) and Mediates brain-derived neurotrophic factor (BDNF)-induced axonal elongation.
BDNF/TrkB signaling plays critical roles in axonal outgrowth of neurons, the process of which requires the remodeling of the cytoskeleton structure, including microtubules and filamentous actin. However, the mechanism by which BDNF/TrkB signaling regulates cytoskeleton reorganization is still unclear. Here, we identified a novel interaction between LIMK1 and TrkB, which is required for the BDNF...
متن کاملDiscovery of Novel Small-Molecule Inhibitors of LIM Domain Kinase for Inhibiting HIV-1
A dynamic actin cytoskeleton is necessary for viral entry, intracellular migration, and virion release. For HIV-1 infection, during entry, the virus triggers early actin activity by hijacking chemokine coreceptor signaling, which activates a host dependency factor, cofilin, and its kinase, the LIM domain kinase (LIMK). Although knockdown of human LIM domain kinase 1 (LIMK1) with short hairpin R...
متن کاملCXCL12/CXCR4 signaling counteracts docetaxel-induced microtubule stabilization via p21-activated kinase 4-dependent activation of LIM domain kinase 1
Emerging data highlight the significance of chemokine (C-X-C motif) ligand 12/chemokine (C-X-C motif) receptor 4 (CXCL12/CXCR4) signaling axis in the chemoresistance of several malignancies, including prostate cancer (PCa); however, underlying mechanisms remain largely elusive. Here, we demonstrate that CXCL12 treatment rescues the PCa cells from docetaxel (DTX)-induced toxicity by overriding i...
متن کاملDownregulation of LIM kinase 1 suppresses ocular inflammation and fibrosis
PURPOSE The purpose of this study was to determine if downregulation of LIM kinase 1 (LIMK1) by genetic deletion or direct application of LIMK1-targeted siRNA could suppress TGF-beta mediated ocular inflammation and fibrosis. METHODS LIMK1 specific siRNAs designed from the human sequence were transfected into human corneal fibroblasts in culture. Immunofluorescence and immunoblotting were per...
