IFIT1 [MD54R]
Description IFIT1, also known as GARG-16, Glucocorticoid-attenuated response gene 16 protein or Interferon-induced 56 kDa protein, IFI-56K, or P56, and encoded by the gene lfit1/Garg16, Ifi56, Isg56, is an interferon-induced antiviral RNA-binding protein that specifically binds single-stranded RNA bearing a 5'-triphosphate group (PPP-RNA), thereby acting as a sensor of viral single-stranded RNAs and inhibiting expression of viral messenger RNAs. Single-stranded PPP-RNAs, which lack 2'-O-methylation of the 5' cap and bear a 5'-triphosphate group instead, are specific from viruses, providing a molecular signature to distinguish between self and non-self mRNAs by the host during viral infection. IFIT1 directly binds PPP-RNA in a non-sequence-specific manner. Viruses evolved several ways to evade this restriction system such as encoding their own 2'-O-methylase for their mRNAs or by stealing host cap containing the 2'-O-methylation (cap snatching mechanism). IFIT1 is a component of an interferon-depen Host Rabbit Application Immunohistochemistry (IHC), Immunoprecipitation (IP), Western Blot (WB) Reactivity Human -
