DESCRIPTION

Also known as MOES_HUMAN, MSN. Ezrin-radixin-moesin (ERM) family protein that connects the actin cytoskeleton to the plasma membrane and thereby regulates the structure and function of specific domains of the cell cortex. Tethers actin filaments by oscillating between a resting and an activated state providing transient interactions between moesin and the actin cytoskeleton (PubMed:10212266). Once phosphorylated on its C-terminal threonine, moesin is activated leading to interaction with F-actin and cytoskeletal rearrangement (PubMed:10212266). These rearrangements regulate many cellular processes, including cell shape determination, membrane transport, and signal transduction (PubMed:12387735, PubMed:15039356). The role of moesin is particularly important in immunity acting on both T and B-cells homeostasis and self-tolerance, regulating lymphocyte egress from lymphoid organs (PubMed:9298994, PubMed:9616160). Modulates phagolysosomal biogenesis in macrophages (By similarity). Participates also in immunologic synapse formation (PubMed:27405666). In resting T-cells, part of a PAG1-SLC9A3R1-MSN complex which is disrupted upon TCR activation. Interacts with SLC9A3R1 (PubMed:9314537, PubMed:15020681). Interacts with PPP1R16B (PubMed:18586956). Interacts with PDZD8. Interacts with SELPLG and SYK; these interaction mediate the activation of SYK by SELPLG (PubMed:12387735). Interacts with PDPN (via cytoplasmic domain); this interaction activates RHOA and promotes epithelial-mesenchymal transition (PubMed:17046996). Interacts with SPN/CD43 cytoplasmic tail (PubMed:9616160, PubMed:11728332). Interacts with CD44 (PubMed:9298994). Interacts with ICAM2 (By similarity). Interacts with ICAM3 (via C-terminus) (PubMed:9298994). Interacts with PDZD8 (PubMed:21549406). Interacts with F-actin (PubMed:10212266). Interacts with CD46 (PubMed:7884872). Interacts with PTPN6 (By similarity).
