Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: Interferon lambda

Structural domains comprising this superfamily share the structure of interferon lambda (IFN)-lambda proteins, which belong to the new type III IFN group. In contrast to type I or type II, the response to type III IFN is cell-type specific and only epithelial-like cells and some immune cells respond to IFN-lambda PMID:22190970. Four distinct proteins designated IFN-lambda1 (interleukin-29, IL-29), IFN-lambda2 (IL-28A), IFN_lambda3 (IL-28B) and IFNL4 have been identified in humans PMID:20712453,PMID:12469119,PMID:23291588. IFN-lambda proteins activate IFN-stimulated gene factor 3 (ISGF3), and are able to induce antiviral protection and MHC class I antigen expression PMID:22190970.
