Gene Summary: This gene encodes a subunit of a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. The cytokine is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family. This cytokine is required for the T-cell-independent induction of interferon (IFN)-gamma, and is important for the differentiation of both Th1 and Th2 cells. The responses of lymphocytes to this cytokine are mediated by the activator of transcription protein STAT4. Nitric oxide synthase 2A (NOS2A/NOS2) is found to be required for the signaling process of this cytokine in innate immunityGeneral information above from NCBI
Subunit structure: Heterodimer with IL27. IL-27 is a heterodimer composed IL27 and EBI3. EBI3 is also a component of the IL-12 heterodimer. Interacts with SQSTM1.
Subcellular location: Secreted.
Induction: By Epstein-Barr virus (EBV).
Post-translational: Phosphorylated. Phosphorylation is induced by NGF through the MAPK/ERK pathway and modulates interaction with RAB11A.
Involvement in disease: Spastic paraplegia 33, autosomal dominant (SPG33) [MIM:610244]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. Note=The disease is caused by mutations affecting the gene represented in this entry. According to PubMed:18606302, the properties of the variant Val-191 and its frequency in some populations raise doubts on the implication of that gene in the disease.
Sequence similarity: Belongs to the type I cytokine receptor family. Type 3 subfamily.
Contains 2 fibronectin type-III domains.
