General description

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.


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.

Biochem/physiol Actions

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.

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.
