  • 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.

Thank you for your patience. I have been in contact with the originator of this antibody, and below is the detailed antigen retrieval protocol. The method of antigen retrieval was used for IHC-P as following: Deparaffinization 1. Incubate slide at 60? for 60 minutes. 2. Deparaffinize in Xylene for 10 minutes and repeat one more times. 3. Hydrate in 100% alcohol for 5 minutes, in 95% alcohol for 5 minutes, in 85% alcohol for 5 minutes, in 75% alcohol for 5 minutes. 4. Dip into Distill Water for 5 minutes. 5. Dip into TBS (50 mM Tris, 100 mM NaCl, pH 7.6), leave for 5 minutes, and repeat two times. Antigen Retrieval 6. Bring 500 - 2000 ml 10 mM citrate buffer (pH6.0) to the boil in a stainless steel pressure cooker. 7. Put the slide into staining rack and lower into pressure cooker ensuring the slide is well immersed in citrate buffer. 8. When the pressure indicator valve has risen after 3-4 minutes, incubate for 1 minute. 9. Cool the slide naturally to room temperature. 10. Dip into distilled water, leave for 5 minutes, and repeat two times. 11. Dip the slide in TBS for 5 minutes and repeat two times. 12. Immerse slides in 3% H2O2 (in fresh methanol) for 15 minutes at room temperature. 13. Wash with distilled water two times, 5 minutes each time. 14. Wash with TBS (pH 7.6) two times, 5 minutes each time. Staining with Primary Antibody 15. Dilute primary antibody with 3% BSA in TBS. Cover the tissue section on the slide with diluted primary antibody (use 50 – 150µl for each slide). 16. Incubate at 37? for 30 minutes or at room temperature for 60 minutes (The optimal incubation time, incubation temperature, and antibody dilution should be determined by the individual laboratory). 17. Wash with TBS two times, 5 minutes each time. Staining with Secondary Antibody 18. Incubate with 100-200µl Polymer Enhancer. Incubate 30 minutes at 37?. 19. Wash with TBS for 3 times, 5 minutes each time. 20. Incubate with 100-200µl Polymerized HRP and incubate 30 minutes at 37? 21. Wash with TBS for 3 times, 5 minutes each time. 22. Add DAB solution and incubate 3-10 minutes(The reaction progress and the optimal time should be determine according to microscope). 23. Wash with distilled water for 2 times, 5 minutes each time. 24. Counterstain sections in hematoxylin if required,wash with distilled water.Immerse slides in 0.1% HClethanol for 1-10 seconds, wash with distilled water. 25. Dehydrate through 95% ethanol for 1 minute, 100% ethanol for 2×3min, Xylene for 2×3min, and coverslip with mounting medium. I hope that this information helps and please do not hesitate to contact us for more information or advice in the future.
