EZR recombinant protein, derived from the human Ezrin protein, is a key component of the ERM (Ezrin-Radixin-Moesin) family that links the plasma membrane to the actin cytoskeleton. Ezrin (encoded by the *EZR* gene) plays a critical role in maintaining cell shape, adhesion, and motility by regulating membrane-cytoskeleton interactions. Its structure includes an N-terminal FERM domain, which binds membrane proteins like CD44 and ICAMs, and a C-terminal actin-binding domain. The middle α-helical region allows conformational changes, enabling Ezrin to switch between inactive (closed) and active (open) states during cellular processes.
Recombinant EZR is typically produced using expression systems like *E. coli* or mammalian cells, followed by purification via affinity tags (e.g., His-tag). This engineered protein retains native functionality, making it valuable for studying cytoskeletal dynamics, cell signaling, and cancer metastasis, where Ezrin overexpression is linked to poor prognosis. It is also used to develop therapeutic antibodies or inhibitors targeting Ezrin-mediated pathways in diseases such as cancer and autoimmune disorders.
The production of recombinant EZR overcomes challenges associated with isolating native Ezrin, ensuring high purity, consistency, and scalability. Its applications span structural studies, biochemical assays (e.g., protein-protein interaction analyses), and diagnostic tool development. By enabling precise manipulation of Ezrin activity, recombinant EZR contributes to advancing research in cell biology, oncology, and drug discovery.
