BACKGROUND Ezrin, a member of the ezrin-radixin-moesin family, is involved in the metastatic spread of osteosarcoma. Ezrin binds phosphatydil inositol-4,5-bisphosphate (PIP2), a crucial molecule of the phosphoinositide signal transduction pathway. PIP2 levels are regulated by phosphoinositide-specific phospholipase C (PI-PLC) enzymes. PI-PLCε isoform, a well-characterized direct effector of rat...

Membrane modifications in sperm cells represent a key step in sperm capacitation; however, the molecular basis of these modifications is not fully understood. Ezrin is the best-studied member of the ezrin/radixin/merlin family. As a cross-linker between the cortical cytoskeleton and plasma membrane proteins, ezrin contributes to remodeling of the membrane surface structure. Furthermore, activat...

BACKGROUND Ezrin, a member of the ezrin-radixin-moesin family, is implicated in tumor progression, metastatic dissemination, and adverse outcomes, in several cancer types. In this study, we explored the clinicopathological significance of ezrin expression in non-small cell lung carcinomas (NSCLCs). METHODS Immunohistochemical analysis of tissue microarray with 112 surgically resected NSCLC sp...

Ezrin, previously also known as cytovillin, p81, and 80K, is a cytoplasmic protein enriched in microvilli and other cell surface structures. Ezrin is postulated to have a membrane-cytoskeleton linker role. Recent findings have also revealed that the NH2-terminal domain of ezrin is associated with the plasma membrane and the COOH-terminal domain with the cytoskeleton (Algrain, M., O. Turunen, A....

Ezrin, a membrane-cytoskeleton linker, is required for cell morphogenesis, motility, and survival through molecular mechanisms that remain to be elucidated. Using the N-terminal domain of ezrin as a bait, we found that p125 focal adhesion kinase (FAK) interacts with ezrin. We show that the two proteins coimmunoprecipitate from cultured cell lysates. However, FAK does not interact with full-leng...

Nonenzymatic glycation of proteins to form advanced glycation end products (AGE) is implicated in diabetic complications, including nephropathy. It was shown recently that AGE bind to the ERM (ezrin, radixin, and moesin) family of membrane-cytoskeletal linker proteins in renal homogenates. Herein is reported the effects of AGE-BSA on ezrin-dependent LLC-PK1 kidney epithelial cellular functions:...

This study was undertaken to observe the effects and the possible mechanism of membrane-cytoskeleton linker ezrin on the chemokine CC chemokine ligand 5 (CCL5)-induced invasive ability in human breast carcinoma MCF-7 cells. RNA interference (RNAi) using ezrin small hairpin RNAs (ezrin shRNA) was used to analyze the role of ezrin in the regulation of this CCL5-induced malignant behavior of MCF-7...

The association between podoplanin and ezrin in the process of odontogenic tumors invasion has been suggested, but was not studied yet. Our purpose was to investigate the relationship between podoplanin and ezrin expressions in the odontogenic epithelium of ameloblastomas. Forty-seven ameloblastomas were analyzed by immunohistochemistry using anti-podoplanin and anti-ezrin antibodies. The expre...

Neuronal morphogenesis is implicated in neuronal function and development with rearrangement of cytoskeletal organization. Ezrin, a member of Ezrin/Radixin/Moesin (ERM) proteins links between membrane proteins and actin cytoskeleton, and contributes to maintenance of cellular function and morphology. In cultured hippocampal neurons, suppression of both radixin and moesin showed deficits in grow...

CLIC5A (encoded by CLIC5) is a component of the ezrin-NHERF2-podocalyxin complex in renal glomerular podocyte foot processes. We explored the mechanism(s) by which CLIC5A regulates ezrin function. In COS-7 cells, CLIC5A augmented ezrin phosphorylation without changing ezrin abundance, increased the association of ezrin with the cytoskeletal fraction and enhanced actin polymerization and the for...
