Background: IL-31RA

The interleukin-31 receptor A subunit (IL-31 RA), also known as gp130-Like Monocyte Receptor (GLM-R or GPL), is a ~100 kDa type I transmembrane glycoprotein that is classified as being a type I cytokine receptor (1, 2). A heterodimeric complex of IL-31 RA and the oncostatin M receptor (OSM R) functions as the signaling receptor for IL-31 (3). Both subunits are inducibly expressed throughout the myelomonocytic lineage and are up-regulated by interferon-gamma and bacterial lipopolysaccharides (1-3). IL-31 RA is also expressed on keratinocytes, dorsal root ganglia neurons, and variably on lung epithelial cells (3-6). The 716 amino acid (aa) mouse IL-31 RA contains an 18 aa signal sequence, a 481 aa extracellular domain (ECD), a 21 aa transmembrane domain and a 196 aa cytoplasmic domain. The ECD of mouse IL-31 RA shares 60% and 84% aa identity with human and rat IL-31 RA ECD, respectively. Mouse IL-31 receptors do not respond to human IL-31 (7). The ECD contains five fibronectin type III domains; the first two contain four conserved cysteine residues and a WSXWS motif common to type I cytokine receptors (2).  In both humans and transgenic mice, IL-31 from skin-homing Th2 cells may contribute to the pruritis (itching) associated with nonatopic dermatitis, especially in infected skin (3, 8, 9).
