Application Abreviews Notes
WB 1/500. Detects a band of approximately 75 kDa (predicted molecular weight: 73 kDa).

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
    modifications
    Autophosphorylated.
    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.

    Rabbit polyclonal to LIM kinase (1/500) - ab10561. 18 ug of mouse brain lysate loaded. Expected mol weight : 73 kD. Bands observed at 75 kD which we believe represents LIM kinase (doublet - may indicate modification such as phosphorylation) and 25 kD (we do not know the identity of this band). Secondary ab - Goat polyclonal to rabbit IgG (HRP) preabsorbed
