Interferon-lambda is functionally an interferon but structurally related to the IL-10 family

Structural highlights

3hhc is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Gene:	IL28B, IFNL3, IFNL4, IL28C, ZCYTO22 (Homo sapiens)
Resources:	FirstGlance, OCA, RCSB, PDBsum

Function

[IL28B_HUMAN] Cytokine with immunomodulatory activity. Up-regulates MHC class I antigen expression. Displays potent antiviral activity. Also displays antitumor activity. 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.^[1] ^[2]

Publication Abstract from PubMed

Interferon-lambda (IFN-lambda) is an antiviral cytokine that signals through a distinct receptor complex, composed of the IFN-lambdaR1 and interleukin-10R2 (IL-10R2) receptor chains. We have determined the crystal structure of human IFN-lambda3 and characterized the interaction with its receptor complex through structure-based site-directed mutagenesis. The ability of IFN-lambda3 mutants to signal was determined by measuring the antiviral activity and induced STAT2 phosphorylation. In conclusion, our data show that, although IFN-lambda is functionally an interferon, it is clearly structurally related to members of the IL-10 family. In particular, we found an interesting similarity between IFN-lambda and IL-22, and we suggest that IFN-lambda and IL-22 possess parallel functions, protecting epithelial tissue against viral and bacterial infections, respectively.
