UniProt functional annotation for Q8IU57



	UniProt functional annotation for Q8IU57

UniProt code: Q8IU57.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: The IFNLR1/IL10RB dimer is a receptor for the cytokine ligands IFNL2 and IFNL3 and mediates their antiviral activity. The ligand/receptor complex stimulate the activation of the JAK/STAT signaling pathway leading to the expression of IFN-stimulated genes (ISG), which contribute to the antiviral state. Determines the cell type specificity of the lambda interferon action. Shows a more restricted pattern of expression in the epithelial tissues thereby limiting responses to lambda interferons primarily to epithelial cells of the respiratory, gastrointestinal, and reproductive tracts. 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. {ECO:0000269|PubMed:12469119, ECO:0000269|PubMed:12483210, ECO:0000269|PubMed:12521379}.

Subunit: Heterodimer with IL10RB. {ECO:0000269|PubMed:12469119, ECO:0000269|PubMed:12483210, ECO:0000269|PubMed:20934432}.

Subcellular location: Membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}.

Tissue specificity: Widely expressed. {ECO:0000269|PubMed:12469119, ECO:0000269|PubMed:12483210}.

Similarity: Belongs to the type II cytokine receptor family. {ECO:0000305}.

Sequence caution: Sequence=BAD18707.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
