ID:IL6RA_HUMAN DESCRIPTION: RecName: Full=Interleukin-6 receptor subunit alpha; Short=IL-6 receptor subunit alpha; Short=IL-6R subunit alpha; Short=IL-6R-alpha; Short=IL-6RA; AltName: Full=IL-6R 1; AltName: Full=Membrane glycoprotein 80; Short=gp80; AltName: CD_antigen=CD126; Flags: Precursor; FUNCTION: Part of the receptor for interleukin 6. Binds to IL6 with low affinity, but does not transduce a signal. Signal activation necessitate an association with IL6ST. Activation may lead to the regulation of the immune response, acute-phase reactions and hematopoiesis. FUNCTION: Low concentration of a soluble form of IL6 receptor acts as an agonist of IL6 activity. SUBUNIT: Hexamer of two molecules each of IL6, IL6R and IL6ST. SUBCELLULAR LOCATION: Isoform 1: Basolateral cell membrane; Single-pass type I membrane protein. SUBCELLULAR LOCATION: Isoform 2: Secreted. TISSUE SPECIFICITY: Isoform 2 is expressed in peripheral blood mononuclear cells and weakly found in urine and serum. DOMAIN: The two fibronectin type-III-like domains, contained in the N-terminal part, form together a cytokine-binding domain. DOMAIN: The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell- surface receptor binding. PTM: A short soluble form may also be released from the membrane by proteolysis. POLYMORPHISM: Genetic variations in IL6R determine soluble IL6R serum levels [MIM:614689]. POLYMORPHISM: Genetic variations in IL6R define the IL6 serum level quantitative trait locus [MIM:614752]. SIMILARITY: Belongs to the type I cytokine receptor family. Type 3 subfamily. SIMILARITY: Contains 1 fibronectin type-III domain. SIMILARITY: Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
