Ezrin Antibody #3145
|W IP IHC-P IF-IC F||H M R Mk B||Endogenous||81||Rabbit|
Reactivity Key: H=Human M=Mouse R=Rat Mk=Monkey B=Bovine
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Ezrin Antibody detects endogenous levels of total ezrin protein. This antibody does not cross-react with ezrin homologues such as radixin and moesin.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human ezrin. Antibodies are purified by protein A and peptide affinity chromatography.

The ezrin, radixin, and moesin (ERM) proteins function as linkers between the plasma membrane and the actin cytoskeleton and are involved in cell adhesion, membrane ruffling, and microvilli formation (1). ERM proteins undergo intra or intermolecular interaction between their amino- and carboxy-terminal domains, existing as inactive cytosolic monomers or dimers (2). Phosphorylation at a carboxy-terminal threonine residue (Thr567 of ezrin, Thr564 of radixin, Thr558 of moesin) disrupts the amino- and carboxy-terminal association and may play a key role in regulating ERM protein conformation and function (3,4). Phosphorylation at Thr567 of ezrin is required for cytoskeletal rearrangements and oncogene-induced transformation (5). Ezrin is also phosphorylated at tyrosine residues upon growth factor stimulation. Phosphorylation of Tyr353 of ezrin transmits a survival signal during epithelial differentiation (6).
