• Product name
    Anti-LIM kinase 1 + 2 antibody
  • Description
    Rabbit polyclonal to LIM kinase 1 + 2
  • Host species
  • Specificity
    Detects endogenous levels of total LIMK1 and LIMK2 proteins. Ab51200 is produced using a phospho peptide immunogen. The phospho-specific antibody is removed by affinity column and pan antibody was purified by non-phospho-peptide columns. This antibody will therefore react with both phosphorylated and non phosphorylated forms of LIMK1 and LIMK2 proteins.
  • Tested applications
    Suitable for: ELISA, IHC-P, WBmore details
  • Species reactivity
    Reacts with: Human
    Predicted to work with: Mouse, Rat
  • Immunogen

    Synthesized non-phosphopeptide derived from human LIMK1 and LIMK2 around the phosphorylation site of threonine 508/505 (R-Y-TP-V-V).

  • Positive control
    • Human breast carcinoma tissue Extracts from cos7 cells

  • Relevance
    LIMK 1 & 2 likely regulate aspects of the cytoskeleton, through control of the organization of actin filaments. They can phosphorylate an actin-binding protein, cofilin which binds to actin monomers and polymers and promotes the disassembly of actin filament.The phosphorylation of cofilin via LIMK inactivates this potential. LIMK1 is highly active in the brain and spinal chord, where it is believed to be involved in the development of nerve cells whilst LIMK2 is ubiquitously expressed in many adult tissues. LIMK1 may play an important role in areas of the brain that are responsible for processing visual-spatial information (visuospatial constructive cognition). These parts of the brain are important for visualizing an object as a set of parts and performing tasks such as writing, drawing, constructing models, and assembling puzzles. LIMK1 is specifically stimulated by Rac, one of the Rho family proteins, while LIMK2 activity is activated under the control of other Rho family members, Rho and Cdc42, suggesting that two distinct pathways exist in the Rho family driven actin cytoskeleton dynamics.
  • Cellular localization
    LIMK1 Cytoplasmic LIMK2 Cytoplasmic and Nuclear. Isoform LIMK2a is distributed in the cytoplasm and the nucleus, and isoform LIMK2b occurs mainly in the cytoplasm and is scarcely translocated to the nucleus.
