  Representation of the IL22RA1 gene organization. IL22RA1 gene and RNA.
Description The gene spans a region of 23.3 kb including seven exons.
Transcription One only transcript form containing 7 exons has been described. The last exon is partially untranslated. The transcript length is 1725 nucleotides, encoding a protein of 594 amino acid residues.
Pseudogene None.


  IL22RA1 protein organization and localization. IL22RA1 protein domains.
Description IL22RA1 is composed of 574 amino acid residues, and the predicted molecular weight of the immature protein is 63 kDa. IL22RA1 protein is composed of six putative domains, including the signal peptide (residue 1 to 15), the extracellular domain (residue 16 to 228), the transmembrane domain (residue 229 to 249), the cytoplasmic domain (residue 250 to 574), and two fibronectin type-III domains (residue 18-115 and 141-221).

Expression IL22RA1 expression is relatively restricted, being found at the highest level in the pancreas, small intestine, colon, kidney, and liver. Importantly, IL22RA1 is not detectable in normal immune cells, including monocytes, B-cells, T-cells, natural killer cells, macrophages and dendritic cells, cell types that are normally found in the bone marrow, peripheral blood, thymus and spleen.

Localisation IL22RA1 is localized at the plasma membrane.
  Localization of IL22RA1 by immunufluorescence confocal microscopy in ALK+ALCL cells.
Function IL22RA1 is one of the subunits of the IL20, IL22 and IL24 receptor complex. Cytokine binding to IL22RA1 results in its aggregation, which activates the associated JAK via its autophosphorylation. This in turn leads to the phosphorylation and activation of STAT proteins. Subsequently, phosphorylated STAT proteins dimerize and translocate to the nucleus to modulate the transcription of various target genes.
  IL22RA1 signaling.


Note Site-directed mutagenesis experiments have revealed critical amino acid residues involved in its binding to IL22. Specifically, mutation of residue 58 from K to A reduces the binding of IL22. Mutation of the residue 60 from Y to A or R results in a complete loss of response to IL22.
Natural IL22RA1 variants have been reported, including those carrying mutations at the residue 130 (S to P), 205 (V to I), 209 (A to S), 222 (L to P), 407 (M to V) and 518 (R to G).

Implicated in

Entity ALK-positive anaplastic large cell lymphoma (ALK+ALCL)
Disease Anaplastic lymphoma kinase (ALK)-positive anaplastic large-cell lymphoma (ALCL), or ALK+ALCL, is a specific type of non-Hodgkin lymphoma characterized by the T/null-cell immunophenotype, consistent expression of CD30 and reciprocal chromosomal translocations involving the ALK gene. In most cases, the chromosomal translocation is that of the , which leads to the juxtaposition of the nucleophosmin (NPM) gene at 5q35 with the ALK gene at 2p23. Mounting evidence suggests that the resulted oncogenic fusion protein, NPM-ALK, plays crucial roles in the pathogenesis of these tumors.
Prognosis Patients with ALK+ALCL are typically treated with combination chemotherapy containing doxorubicin. ALK+ALCL represents one of the most common pediatric lymphoid malignancies. The prognosis of pediatric ALK+ALCL patients is significant better than that of adult patients.
Cytogenetics t(2;5)(p23;q35) in most ALK+ALCL patients; other translocation variants have been described.

Abnormal Protein NPM-ALK
Structure of the oncogenic fusion protein NPM-ALK.
Oncogenesis Aberrant expression of IL22RA1 in ALK+ALCL lymphoma cells allows these cells to be responsive to IL-22 stimulation, which further stimulate STAT3 signaling and the growth of these cells. Blocking the IL-22 signaling pathway using a neutralizing antibody has been shown to significantly decrease the growth of ALK+ALCL cells in-vitro. The aberrant expression of IL22RA1 in ALK+ALCL is dependent on the expression of NPM-ALK, since siRNA to downregulate NPM-ALK dramatically shut down IL22RA1 expression.
