IFITM2 (Interferon Induced Transmembrane Protein 2): IFITM2 is part of the interferon-induced transmembrane protein family that plays a crucial role in the body's defense against viral infections. It is involved in inhibiting the replication and spread of various enveloped viruses within host cells. IFITM2 functions by blocking the fusion of viral membranes with host cell membranes, a critical step in the viral life cycle. Its expression is upregulated in response to interferon, highlighting its role in the innate immune response to viral infections....
