Interleukin 10 Receptor, Beta Subunit
Interleukin 10 receptor, beta subunit is a subunit for the interleukin-10 receptor. IL10RB is its human gene. IL10RB has also been designated CDw210b (cluster of differentiation w210b). The protein encoded by this gene belongs to the cytokine receptor family. It is an accessory chain essential for the active interleukin 10 receptor complex. Coexpression of this and IL10RA proteins has been shown to be required for IL10-induced signal transduction. This gene and three other interferon receptor genes, ''IFNAR2'', ''IFNAR1 Interferon-alpha/beta receptor alpha chain is a protein that in humans is encoded by the ''IFNAR1'' gene.

Interleukin-10 Receptor
Interleukin-10 receptor (IL-10R) is a type II cytokine receptor. The receptor is tetrameric, composed of 2 α and 2 β subunits. The α subunit (encoded in the ''Il10ra gene)'' is expressed on haematopoietic cells (such as T, B, NK, mast, and dendritic cells) whilst the β subunit (encoded in the ''Il10rb gene'') is expressed ubiquitously. The α subunit is exclusive to interleukin-10, however the β subunit is shared with other type II cytokine receptors such as IL-22R, IL-26R and INFλR. The IL-10R α subunit acts as the ligand binding site and may be upregulated in various cell types as necessary. The IL-10R β functions as the signaling subunit and is constitutively expressed in a majority of cell types. There is evidence that upon ligand binding at the α subunit, a conformational change occurs in the β subunit that allows it to additionally bind to IL-10. This structure forms a heterotetramer that leads to the signaling complex activation of JAK1 and TYK2 kinase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cluster Of Differentiation
The cluster of differentiation (also known as cluster of designation or classification determinant and often abbreviated as CD) is a protocol used for the identification and investigation of cell surface molecules providing targets for immunophenotyping of cells. In terms of physiology, CD molecules can act in numerous ways, often acting as receptors or ligands important to the cell. A signal cascade is usually initiated, altering the behavior of the cell (see cell signaling). Some CD proteins do not play a role in cell signaling, but have other functions, such as cell adhesion. CD for humans is numbered up to 371 (). Nomenclature The CD nomenclature was proposed and established in the 1st International Workshop and Conference on Human Leukocyte Differentiation Antigens (HLDA), held in Paris in 1982. This system was intended for the classification of the many monoclonal antibodies (mAbs) generated by different laboratories around the world against epitopes on the surface mo ...

Cytokine Receptor
Cytokine receptors are receptors that bind to cytokines. In recent years, the cytokine receptors have come to demand the attention of more investigators than cytokines themselves, partly because of their remarkable characteristics, and partly because a deficiency of cytokine receptors has now been directly linked to certain debilitating immunodeficiency states. In this regard, and also because the redundancy and pleiotropy of cytokines are a consequence of their homologous receptors, many authorities are now of the opinion that a classification of cytokine receptors would be more clinically and experimentally useful. Classification A classification of cytokine receptors based on their three-dimensional structure has been attempted. (Such a classification, though seemingly cumbersome, provides several unique perspectives for attractive pharmacotherapeutic targets.) * Type I cytokine receptors, whose members have certain conserved motifs in their extracellular amino-acid domain. ...

IL10RA
Interleukin-10 receptor subunit alpha is a subunit for the interleukin-10 receptor. ''IL10RA'' is its human gene. IL10RA has also been designated CDw210a (cluster of differentiation w210a). Function The protein encoded by this gene is a receptor for interleukin 10. This protein is structurally related to interferon receptors. It has been shown to mediate the immunosuppressive signal of interleukin 10, and thus inhibits the synthesis of proinflammatory cytokines. This receptor is reported to promote survival of myeloid progenitor cells through the insulin receptor substrate-2/PI 3-kinase/AKT pathway. Activation of this receptor leads to tyrosine phosphorylation of JAK1 and TYK2 kinases. Interactions Interleukin 10 receptor, alpha subunit has been shown to interact with: * Interleukin 10 and * Janus kinase 1 Janus kinase 1 (JAK1) is a human tyrosine kinase protein essential for signaling for certain type I and type II cytokines.

Class II Cytokine Receptor
Type II cytokine receptors, also commonly known as class II cytokine receptors, are transmembrane proteins that are expressed on the surface of certain cells. They bind and respond to a select group of cytokines including interferon type I, interferon type II, interferon type III. and members of the interleukin-10 family These receptors are characterized by the lack of a WSXWS motif which differentiates them from type I cytokine receptors. Structure Typically type II cytokine receptors are heterodimers or multimers with a high and a low affinity component. These receptors are related predominantly by sequence similarities in their extracellular portions that are composed of tandem Ig-like domains. The structures for the extracellular domains of the receptors for interferon types, I, II, and III are all known. Type II cytokine receptors are tyrosine-kinase-linked receptors. The intracellular domain of type II cytokine receptors is typically associated with a tyrosine kinas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
