Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Moesin Antibody detects endogenous levels of total moesin protein. The antibody does not cross-react with ezrin, radixin or other related proteins.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues surrounding His670 of human moesin. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from HeLa, HEK293, NIH/3T3, L929, C6, PC12, and COS cells, using Moesin Antibody.
Flow Cytometry
Flow cytometric analysis of untreated Jurkat cells, using Moesin Antibody (blue) compared to a nonspecific negative control antibody (red).
Background
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 their 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).
