Interleukin-31 Receptor
The interleukin-31 receptor (IL-31R) is a receptor bound and activated by interleukin-31 (IL-31). It is a heterodimer consisting of IL-31 receptor A (IL31RA) and oncostatin M receptor Oncostatin-M specific receptor subunit beta also known as the Oncostatin M receptor (OSMR) , is one of the receptor proteins for oncostatin M, that in humans is encoded by the ''OSMR'' gene. OSMR is a member of the type I cytokine receptor famil ... subunits. References Cytokine receptors {{membrane-protein-stub ...

Receptor (biochemistry)
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. These signals are typically chemical messengers which bind to a receptor and cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell. There are three main ways the action of the receptor can be classified: relay of signal, amplification, or integration. Relaying sends the signal onward, amplification increases the effect of a single ligand, and integration allows the signal to be incorporated into another biochemical pathway. Receptor proteins can be classified by their location. Transmembrane receptors include ligand-gated ion channels, G protein-coupled receptors, and enzyme-linked hormone receptors. Intracellular receptors are those found inside the cell, and include cytoplasmic receptors and nuclear receptors. A molecule that binds to a receptor is called a ligand ...

Interleukin-31
Interleukin-31 (IL-31) is a protein that in humans is encoded by the ''IL31'' gene that resides on chromosome 12. IL-31 is an inflammatory cytokine that helps trigger cell-mediated immunity against pathogens. It has also been identified as a major player in a number of chronic inflammatory diseases, including atopic dermatitis. IL-31 is produced by a variety of cells, namely type 2 helper ( TH2) T-cells. IL-31 sends signals through a receptor complex made of IL-31RA and oncostatin M receptor β (OSMRβ) expressed in immune and epithelial cells. These signals activate three pathways: ERK1/2 MAP kinase, PI3K/AKT, and JAK1/ 2 signaling pathways. Structure IL-31 is a cytokine with an anti-parallel four-helix bundle structure in the gp130/IL-6 cytokine family. This family includes IL-6, IL-11, IL-27, leukemia inhibitory factor (LIF), oncostatin M (OSM), ciliary neurotrophic factor (CNTF), cardiotrophin-1 (CT-1), cardiotrophin-like cytokine (CLC), and neuropoietin (NP).

Heterodimer
In biochemistry, a protein dimer is a macromolecular complex formed by two protein monomers, or single proteins, which are usually non-covalently bound. Many macromolecules, such as proteins or nucleic acids, form dimers. The word ''dimer'' has roots meaning "two parts", '' di-'' + '' -mer''. A protein dimer is a type of protein quaternary structure. A protein homodimer is formed by two identical proteins. A protein heterodimer is formed by two different proteins. Most protein dimers in biochemistry are not connected by covalent bonds. An example of a non-covalent heterodimer is the enzyme reverse transcriptase, which is composed of two different amino acid chains. An exception is dimers that are linked by disulfide bridges such as the homodimeric protein NEMO. Some proteins contain specialized domains to ensure dimerization (dimerization domains) and specificity. The G protein-coupled cannabinoid receptors have the ability to form both homo- and heterodimers with several typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IL31RA
Interleukin-31 receptor A is a protein that in humans is encoded by the ''IL31RA'' gene In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b .... IL31RA is related to gp130 (IL6ST; MIM 600694), the common receptor subunit for IL6 (MIM 147620)-type cytokines. Oncostatin M receptor (OSMR; MIM 601743) and IL31RA form the heterodimeric receptor through which IL31 (MIM 609509) signals. Expression of IL31RA and OSMR mRNA is induced in activated monocytes, and both mRNAs are constitutively expressed in epithelial cells (Dillon et al., 2004). upplied by OMIMref name="entrez"> References Further reading * * * * * * * * {{gene-5-stub ...

Oncostatin M Receptor
Oncostatin-M specific receptor subunit beta also known as the Oncostatin M receptor (OSMR) , is one of the receptor proteins for oncostatin M, that in humans is encoded by the ''OSMR'' gene. OSMR is a member of the type I cytokine receptor family. This protein heterodimerizes with interleukin 6 signal transducer to form the type II oncostatin M receptor and with interleukin 31 receptor A to form the interleukin 31 receptor, and thus transduces oncostatin M and interleukin 31 induced signaling events. Expression OSMR is widely expressed across non-haematopoietic, hepatocytes, mesothelial cells, glial cells and epithelial cell types across various organs and mammary glands. OSM receptor is abundantly expressed on endothelial and stromal/fibroblast cells in the lung of mice.= In vitro expression of OSMR in fetal hepatocytes is upregulated by OSM stimulation. OSMR expression has been shown to be induced by parathyroid hormone in osteoblasts and OSM. Signaling Intracellula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
