Anti-LIMK2 antibodies are used in the immunodetection of the protein LIM domain kinase 2. In humans, the canonical protein has a reported length of 638 amino acid residues and a mass of 72.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the TKL Ser/Thr protein kinase protein family, LIMK2 is a type of serine/threonine-protein kinase that plays an essential role in the regulation of actin filament dynamics. Post-translational modifications have been described, including phosphorylation. LIMK2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 150 citations in the literature describe the use of LIMK2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
