background:
IL-28R is a 535 amino acid protein encoded by the human gene IL28RA. IL-28R belongs to the type II cytokine receptor family and contains 1 fibronectin type-III domain. It is a single-pass type I membrane protein found as a heterodimer with IL-10RB. This is a receptor for a small family of structurally-related cytokines that, like IFNs, are known to induce antiviral activity. The expression of IFN-I (IL-28) mRNA is inducible by viral infection in several cell lines. The receptor complex (IL-28R) that is utilized by all three IFN-l proteins for signaling is composed of two subunits, a receptor designated IL-28R and IL-10R2. Both receptor chains are constitutively expressed on a wide variety of human cell lines and tissues and signal through the Jak-STAT (Janus kinases-signal transducers and activators of transcription) pathway.
Function:
IL28RA is a class II cytokine receptor that interacts with IL10RB to bind IL28A, IL28B, and IL29, which are related to type I interferons. These ligands play a critical role in response to microbial challenge and activate the JAK/STAT signaling system. It heterodimers with IL10RB. There are 4 isoforms as result of alternative splicing. It is widely expressed. IL28RA belongs to the type II cytokine receptor family, and contains 1 fibronectin type III domain.

Heterodimer with IL10RB.

Membrane; Single-pass type I membrane protein
