Description_x000D_ General description_x000D_ FBLIM1 (filamin binding LIM protein 1) is present at the cell-cell adhesion areas. The protein has the amino-terminal, proline rich-region and carboxy-terminal LIM (LIN-11, ISL-1 and MEC-3) domains. It is commonly referred to as migfilin._x000D_ Immunogen_x000D_ recombinant human migfilin, fusion protein.1 The isotype is determined by ELISA using Mouse Monoclonal Antibody Isotyping Reagents (Sigma ISO-2)._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ FBLIM1 (filamin binding LIM protein 1) plays an important role in association between the cell membrane and the actin cytoskeleton. It mainly interacts with MIG-2 (mitogen-inducible gene 2 protein), filamin and VASP (vasodilator-stimulated phosphoprotein), thus controlling cell shape and movements. In cardiomyocytes, it interacts with transcription factor CSX/NKX2-5 (cardiac-specific homeobox) and enhances the differentiation. The FBLIM1 gene is upregulated in osteoarthritis chondrocytes and might be involved with osteoarthritis pathogenesis. In various carcinoma cells, the FBLIM1-associated signaling in disrupted which leads to abnormal Src activation and anoikis resistance in cells. This gene is downregulated in breast cancer cells. In esophageal cancer cells, it suppresses invasion partly by enhancing degradation of β-catenin. However, in glioma cells FBLIM1 promotes migration as well as invasion.
