Phospho-Moesin (Thr558) antibodies are essential tools for studying the activation and functional regulation of moesin, a member of the ezrin-radixin-moesin (ERM) family of proteins. ERM proteins act as molecular linkers between the plasma membrane and the actin cytoskeleton, playing critical roles in cell adhesion, motility, and signal transduction. Moesin becomes activated through phosphorylation at Thr558. a conserved residue within its C-terminal tail. This phosphorylation event, mediated by Rho-associated kinase (ROCK) and other kinases, induces a conformational change that unmasks binding sites for F-actin and transmembrane proteins, enabling moesin to regulate membrane-cytoskeleton dynamics.

The Phospho-Moesin (Thr558) antibody specifically recognizes moesin when phosphorylated at this site, serving as a marker for its active state. Researchers use this antibody in techniques like Western blotting, immunofluorescence, and flow cytometry to investigate cellular processes such as cell polarity, membrane protrusion, and cancer cell invasion. Its applications extend to studies of pathological conditions, including metastatic cancers, where elevated moesin phosphorylation correlates with enhanced cell migration and poor prognosis. Validation of antibody specificity often involves knockout controls or phosphatase treatment to confirm phosphorylation-dependent signals. By detecting Thr558 phosphorylation, this antibody provides insights into Rho/ROCK signaling pathways and their roles in cytoskeletal remodeling under physiological or disease contexts.
