  • Target

    • Function
      Protein kinase which regulates actin filament dynamics. Phosphorylates and inactivates the actin binding/depolymerizing factor cofilin, thereby stabilizing the actin cytoskeleton. Stimulates axonal outgrowth and may be involved in brain development. Isoform 3 has a dominant negative effect on actin cytoskeletal changes.
    • Tissue specificity
      Highest expression in both adult and fetal nervous system. Detected ubiquitously throughout the different regions of adult brain, with highest levels in the cerebral cortex. Expressed to a lesser extent in heart and skeletal muscle.
    • Involvement in disease
      Note=LIMK1 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region.
    • Sequence similarities
      Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.
      Contains 2 LIM zinc-binding domains.
      Contains 1 PDZ (DHR) domain.
      Contains 1 protein kinase domain.
    • Post-translational
      Phosphorylated on serine and/or threonine residues by ROCK1. May be dephosphorylated and inactivated by SSH1.
      Ubiquitinated. 'Lys-48'-linked polyubiquitination by RNF6 leads to proteasomal degradation through the 26S proteasome, modulating LIMK1 levels in the growth cone and its effect on axonal outgrowth. Also polyubiquitinated by RLIM.
    • Cellular localization
      Cytoplasm. Cell projection > growth cone.

    • ab39641 staining LIM Kinase 1 in the growth cones of Human DRG neurons by Immunocytochemistry/ Immunofluorescence.
      Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature and permeabilized (0.1% Triton X-100 and 1× phosphate-buffered saline). After blocking, cells were incubated for double staining with primary antibodies, followed by incubation with the appropriate Cy3-secondary antibody for 30 minutes and with 4',6-diamidino-2-phenylindole. F-actin staining with Alexa 488-phalloidin.

      Scale bar = 10µm.
