Interferon-induced transmembrane protein 3 (IFITM3) is a protein that in humans is encoded by the IFITM3 gene. It is reported to play a critical role in the immune system’s defense against Swine Flu where heightened levels of IFITM3 keep viral levels low and the removal of IFITM3 allows the virus to multiply unchecked [3].
