Description_x000D_ General description_x000D_ RDX (radixin) belongs to the ERM (ezrin-radixin-moesin) family. It is present in several normal cells, neoplastic cells, epithelial and lymphoid cells. It is located on chromosome 11. In mouse, RDX is found in the hair cell stereocilia of inner ear._x000D_ Immunogen_x000D_ synthetic peptide corresponding to amino acid residues 400-409 of human radixin with an N-terminal added tripeptide, conjugated to KLH. The corresponding sequence is identical in mouse, rat, and pig and differs by two amino acids in chicken._x000D_ Application_x000D_ Anti-Radixin antibody produced in rabbit has been used in_x000D_ • immunoblotting_x000D_ • immunoprecipitation_x000D_ • immunofluorescence staining of cultured cells_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 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_ In human, knockdown of radixin (RDX) represses the development of glioblastoma cell in vitro and in vivo. It participates in cell motility, invasion and tumor progression. It acts as a membrane-cytoskeletal linker in cell surface structures that are abundant with actin. It is necessary for the arrangement of cortical cytoskeleton. RDX mutation can lead to DFNB24 hearing loss in human._x000D_ Radixin is the dominant ezrin-radixin-moesin (ERM) protein in liver bile canaliculi where it is considered to have a critical role in bile conjugated-bilirubin secretion by influencing the cellular localization of the multidrug resistance protein 2 (MRP2). Resting normal human blood cells lack detectable radixin. Radixin is found in classical NK cells. Radixin has closed and open forms corresponding to the inactive and active forms as cross-linkers between actin filaments. It may be phosphorylated and it plays an important role in the activation of the Rho family members by recruiting their positive and negative regulators.
