GENERIF_SUMMARY amino-terminal domains of the ezrin, radixin, and moesin (ERM) proteins bind advanced glycation end products and have a role in diabetes, Disrupted localization of radixin and MRP2 supports the concept that radixin contributes to the canalicular localization of MRP2., ezrin/radixin/moesin proteins are recruited by NHE1 Na+/H+ exchanger and have roles in regulating Akt-dependent cell survival, All three ERM family members can localise to the nucleus; a specific nuclear localisation sequence, which is conserved and functional in all ERM family members, is identified, implying specific regulated nuclear import., results suggest that ezrin-radixin-moesin proteins are required for microvillar positioning of L-selectin and that this is important both for leukocyte tethering

proteins that was dependent upon the expression of ADP-ribosyltransferase activity., 2 mutant alleles of RDX in 2 consanguineous families associated with neurosensory hearing loss; sequence analysis

regulators of infection by X4-tropic HIV-1, Unlike ezrin and moesin, radixin (a member of the ezrin-radixin-moesin protein family)is not expressed in Jurkat cells, nor is it involved in apoptotic signaling following Fas receptor triggering in these cells., No aspects of T cell receptor signaling uniquely require transgenic ezrin or moesin; instead, T cell activation appears to depend on net ezrin, radixin, and moesin (ERM)protein expression, while ezrin and moesin function together., In Vitro and in Vivo Characterization of Molecular Interactions between Calmodulin, Ezrin/Radixin/Moesin,

ezrin-radixin-moesin phosphorylation in regulating cell shape and motility., Data show that stimulation of the NK cell-expressed tetraspanin CD81 induces phosphorylation of ezrin/radixin/moesin proteins and leads to NK cell polarization thereby facilitating NK cell migration toward various chemokines/cytokines., Ezrin, radixin, and moesin proteins are physiological substrates of the kinase activity of leucine-rich repeat kinase 2 (LRRK2)., Results demonstrate a new regulatory mechanism of ezrin-radixin-moesin phosphorylation by sphingolipids with opposing actions of ceramide and sphingosine 1-phosphate., Data suggest that ezrin-radixin-moesin proteins are involved in the spatial regulation of Epac1 and cooperate with cAMP- and Rap-mediated signaling to regulate adhesion to the extracellular matrix., the identification of radixin as a scaffolding unit for both cAMP effectors, Epac and PKA, Polar distribution of radixin suggest a role in promoting formation and plasticity of membrane surface projections and also suggest that radixin is an organizer and regulator of Mrp-2 and cell polarity in hepatocytes., This study provides the novel evidence that increased phosphorylation of Ezrin/radixin/moesin proteins may contribute to proliferation of rheumatoid fibroblast-like synoviocytes., Dysregulation of the ezrin/radixin/moesin-RAGE complex might be an important step in rearrangement of the actin cytoskeleton during proinflammatory cytokine-induced epithelial-mesenchymal transition of human alveolar epithelial cells., ezrin, radixin and moesin play similar roles in the tumor cell metastatic potential and their roles of upregulating the expression of E-cadherin may be important in tumor progression, Ezrin, radixin, and moesin are phosphorylated in response to 2-methoxyestradiol and modulate endothelial hyperpermeability., results indicate that ezrin influences the expression of P-gp at the translational level, whereas radixin is involved in membrane localization of P-gp in HepG2 cells, the ezrin, radixin and moesin proteins differentially modulate sphingosine 1 phosphate-induced alterations in lung endoethlial cell cytoskeleton and permeability, MiR-31 targeted radixin predominantly via inhibition of protein translation instead of degradation of mRNA., The ERM (ezrin, radixin, moesin) proteins are novel scaffolds at the level of SOS activity control, which is relevant for both normal Ras function and dysfunction known to occur in several human cancers., Data show that silencing of radixin (RDX) phenocopied the effects of miR-409 overexpression, whereas restoration of RDX in miR-409-overexpressed gastric cancer (GC) cells reversed the suppressive effects of miR-409., role of CCM3 and ezrin/radixin/moesin family of proteins in cell's response to oxidative stress, Radixin plays an important role in promoting cell migration by regulating Rac1-mediated epithelial polarity and formation of adherens junctions through Vav GEFs., Radixin selectively modulates the expression and function of MRP2 in human gastric adenocarcinoma., results suggest that radixin might play a critical role in pancreatic cancer progression, possibly through involvement of down-regulation of TSP-1 and E-cadherin expression., Ano1, ezrin, and moesin/radixin colocalize apically in salivary gland epithelial cells, and overexpression of moesin and Ano1 in HEK cells alters the subcellular localization of both proteins, Ezrin/radixin/moesin are required for the purinergic P2X7 receptor (P2X7R)-dependent processing of the amyloid precursor protein., Control of adipogenesis by ezrin, radixin and moesin-dependent biomechanics remodeling., Data suggest that P-glycoprotein associate with the F-actin cytoskeleton through

OMIM_DISEASE Deafness, autosomal recessive 24,
SP_COMMENT disease:Defects in RDX are the cause of non-syndromic sensorineural deafness autosomal recessive type 24 (DFNB24) [MIM:611022]. DFNB24 is a form of sensorineural hearing loss.
