背景信息

IFITM2 (Interferon-Induced Transmembrane Protein 2) is a member of the IFITM family, a group of small transmembrane proteins encoded by interferon-stimulated genes (ISGs). These proteins play critical roles in innate immunity, particularly in restricting viral infections. IFITM2 is highly conserved across vertebrates and is broadly expressed in various tissues, with elevated levels observed during immune responses. It localizes to endosomal and lysosomal membranes, where it interferes with viral entry by altering membrane fluidity and preventing fusion of viral envelopes with host cell membranes. Its activity has been implicated in inhibiting diverse enveloped viruses, including influenza A, dengue, Zika, and SARS-CoV-2.

Recombinant IFITM2 protein is produced using biotechnological methods, typically through expression in bacterial or mammalian systems followed by purification. This engineered protein retains the functional domains of native IFITM2. enabling researchers to study its antiviral mechanisms, protein-protein interactions, and post-translational modifications in controlled experimental settings. Structural studies using recombinant IFITM2 have provided insights into its topology, featuring two conserved intracellular loops and a hydrophobic domain critical for its antiviral function.

Research on recombinant IFITM2 has expanded beyond virology, exploring its potential roles in cancer progression, immune regulation, and cellular differentiation. Dysregulation of IFITM2 expression has been associated with certain cancers, suggesting its dual role as both a host defense component and a disease modulator. Current applications include in vitro antiviral assays, mechanistic studies of membrane protein dynamics, and development of diagnostic or therapeutic tools targeting viral infections or IFITM2-related pathologies.
