The protein known as Fragilis also called Interferon-induced transmembrane protein 3 (IFITM3) plays a role in cellular defense mechanisms. Fragilis is approximately 15 kDa in mass. It is commonly expressed in cells of the immune system such as lymphocytes and can also be found in various tissues including the lungs spleen and thymus. This protein includes a chain of functional domains that interact with cellular membranes contributing to its protective roles on the cellular level.
Biological function summary
IFITM3 acts as an antiviral protein that disrupts the life cycle of viruses entering human cells. It is a part of a family of transmembrane proteins that block viral replication by inhibiting the fusion of viral membranes with endosomal membranes. The presence of Fragilis in respiratory epithelial cells is integral to the immune response against viral infections. The protein acts as a barrier to viruses like influenza providing an innate immune defense mechanism.
Pathways
The involvement of IFITM3 is central to the immune signaling pathways specifically the interferon signaling pathway. Upon viral infection interferons upregulate IFITM3 enhancing its antiviral activities. Other proteins like STAT1 and STAT2 mediate this regulation. Additionally IFITM3 aligns with the pathways regulating cell membrane integrity and remodeling highlighting its multi-functional role beyond just antiviral defense.
Research highlights the relevance of IFITM3 in conditions such as influenza and COVID-19. In both cases higher expression levels correlate with better prognosis. For instance variations in IFITM3 expression or genetic mutations can affect susceptibility to severe influenza. Connections with proteins such as MxA and other IFITM proteins can influence these disease processes. These connections make Fragilis a target of interest for understanding and potentially mitigating the severity of viral infections.
