Merck, SRP3203-20UG, IFN-lambda 2 from mouse

Biochem/physiol Actions
IFN-λ 2 (Ifnl2) belongs to the type III interferon (IFN-λ) family of proteins. It is associated with antiviral, antitumor and immune activities. In a retinal autoimmunity mouse model, Ifnl2 increases the autoimmune disease. Ifnl2 signals via IFN (interferon)-λ receptor complex consisting of IL-10Rβ (interleukin 10 receptor β) and the IL-28Rα chains. The signaling pathway involves JAK1 (Janus kinase 1)/TYK2 (non-receptor tyrosine-protein kinase) tyrosine kinases, transcription factor complex IFN-stimulated gene factor 3 containing STAT1 (signal transducer and activator of transcription 1), STAT2 and IFN regulatory factor (IRF)-9.
Recombinant murine IFN-l2 is a 19.8kDa protein containing 175 amino acid residues.
Physical form
Lyophilized from 20 mM Sodium Phosphate, pH 7.5.
