Function

[IFNL1_HUMAN] Cytokine with immunomodulatory activity. May play a role in antiviral immunity. Up-regulates MHC class I antigen expression. Ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1. The ligand/receptor complex seems to signal through the Jak-STAT pathway. [INLR1_HUMAN] The IFNLR1/IL10RB dimer is a receptor for IFNL1, IFNL2 and IFNL3. The ligand/receptor complex seems to signal through the Jak-STAT pathway. Seems not to be essential for early virus-activated host defense in vaginal infection, but plays an important role in Toll-like receptor (TLR)-induced antiviral defense. Plays a significant role in the antiviral immune defense in the intestinal epithelium.^[1] ^[2] ^[3]

Publication Abstract from PubMed

Interferon (IFN)-lambda1 [also known as interleukin (IL)-29] belongs to the recently discovered group of type III IFNs. All type III IFNs initiate signaling processes through formation of specific heterodimeric receptor complexes consisting of IFN-lambdaR1 and IL-10R2. We have determined the structure of human IFN-lambda1 complexed with human IFN-lambdaR1, a receptor unique to type III IFNs. The overall structure of IFN-lambda1 is topologically similar to the structure of IL-10 and other members of the IL-10 family of cytokines. IFN-lambdaR1 consists of two distinct domains having fibronectin type III topology. The ligand-receptor interface includes helix A, loop AB, and helix F on the IFN site, as well as loops primarily from the N-terminal domain and inter-domain hinge region of IFN-lambdaR1. Composition and architecture of the interface that includes only a few direct hydrogen bonds support an idea that long-range ionic interactions between ligand and receptor govern the process of initial recognition of the molecules while hydrophobic interactions finalize it.
