  • Function

    Displays serine/threonine-specific phosphorylation of myelin basic protein and histone (MBP) in vitro.
  • Tissue specificity

    Highest expression in the placenta; moderate level in liver, lung, kidney, and pancreas. LIMK2a is found to be more abundant then LIMK2b in liver, colon, stomach, and spleen, while in brain, kidney, and placenta LIMK2b is the dominant form. In adult lung, both LIMK2a and LIMK2b is nearly equally observed.
  • 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.
  • Cellular localization

    Cytoplasm. Nucleus. Isoform LIMK2a is distributed in the cytoplasm and the nucleus and Cytoplasm. Nucleus. Isoform LIMK2b occurs mainly in the cytoplasm and is scarcely translocated to the nucleus.

  • Lane 1: Wild-type HAP1 whole cell lysate (40 µg)
    Lane 2: LIMK2 (LIMK2) knockout HAP1 whole cell lysate (40 µg)
    Lane 3: Jurkat whole cell lysate (40 µg)

    Lanes 1 - 3: Merged signal (red and green). Green - ab45165 observed at 72 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab45165 was shown to specifically recognize LIMK2 (LIMK2) in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed with knockout cells were examined. Wild-type and LIMK2 (LIMK2) knockout samples were subjected to SDS-PAGE. Ab45165 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/2000 dilution and 1/20,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1/20,000 dilution for 1 hour at room temperature before imaging.

  • ab45165 staining LIMK2 in human ovary carcinoma by immunohistochemistry using paraffin embedded tissue.

  • Immunocytochemistry/ Immunofluorescence analysis of Ramos cells labeling LIMK2 with ab45165 at 1/250. Goat anti rabbit IgG(Alexa Fluor® 488); ab150077 at 1/1000 dilution was used as the secondary antibody. Cells were fixed with 4% paraformaldehyde and permeabilised with 0.1% tritonX-100. DAPI (blue) was used as a nuclear counterstain.


  • Anti-LIMK2 antibody [EP969Y] - C-terminal (ab45165) at 1/2000 dilution + Ramos (Human Burkitt's lymphoma cell line) membrane lysate

    Predicted band size: 72 kDa
    Observed band size: 70 kDa
    why is the actual band size different from the predicted?

  • Immunohistochemical analyis of mouse upper eyelid tissue, staining LIMK2 with ab45165 at 1/200 dilution. Staining was detected using DAB.
