Description
IFN lambda-1, -2, and -3 are distantly related to the IL-10 family and interferons. All three IFN-lambdas use a distinct receptor system composed of an IFN-lambdaR1 subunit (also called CRF2-12) and IL-10R2 subunit (also called CRF2-14) . Signaling through this receptor system induces antiviral defense similar but distinct than the type I interferons (Kotenko, SV. et al. Nat Immunology 2003 [1] p. 69-77) . Recombinant human IFN-lambda 1 is a 19.8 kDa protein containing 178 amino acid residues.
