Ezrin also known as cytovillin or villin-2 is a protein belonging to the ezrin-radixin-moesin (ERM) family. It is approximately 81 kDa in molecular weight. Ezrin plays a critical role in linking the actin cytoskeleton to the plasma membrane. This interaction occurs through its ability to bind to membrane proteins and phospholipids facilitating structural support and signal transduction. Ezrin is widely expressed in epithelial tissues but it also occurs in other cell types such as lymphocytes and osteoclasts.

Biological function summary

Ezrin functions as a membrane-microfilament linker and is essential for maintaining cell shape adhesion and motility. It is an integral component of many cellular structures including microvilli and ruffles. Ezrin’s activity often involves forming complexes with other proteins such as EBP50 and F-actin which are fundamental for its role in cellular morphogenesis. These interactions allow ezrin to regulate membrane surface structure and cell surface organization.

Pathways

Ezrin participates in various signaling pathways that are essential for cell migration and invasion. One key pathway is the Rho family of GTPases which regulates actin cytoskeleton dynamics. Ezrin interacts with proteins like Rho-associated kinase (ROCK) that influence cell contraction and motility. Additionally ezrin is involved in the MAPK/ERK pathway which influences cell growth and survival by interacting with other signaling molecules.

Ezrin shows significant relevance to cancer progression and metastasis particularly in conditions like osteosarcoma. Ezrin overexpression correlates with increased metastatic potential and poor clinical outcomes. It also has implications in allergic diseases due to its role in immune cell function. In these contexts ezrin interacts with SRC family kinases which are important for transmitting signals from cell-surface receptors to downstream pathways influencing disease development and progression.
