Description

Alternate Names:  Type II interferon, T cell interferon, Immune Interferon, MAF               Accession Number: P01581
Description:  Interferon gamma (IFN-γ) is a type II interferon that is critical during adaptive and innate immune responses to infection.  IFN-γ is produced by T cells and natural killer cells following antigen-specific activation.  IFN-γ binds IFN-γ receptors (IFN-γ R1 and IFN-γ R2), which are expressed on most immune cells, to activate the JAK-STAT pathway.  IFN-γ-induced signaling increases the expression of class 1 major histocompatibility complex (MHC) molecules.  
Source:  Genetically modified E.coli.
