Anti-ITPR1 antibody produced in rabbit, 1 X 100 µL (HPA014765-100UL)

ITPR1 (inositol 1,4,5-trisphosphate receptor, type 1) is a ligand-gated calcium channel, which is present in the endoplasmic reticulum (ER). It either acts as a homotetarmer or forms heterotetramer with type 2 or type 3 inositol 1,4,5-trisphosphate receptors. It is highly expressed in the central nervous system, especially in the Purkinje cells of the cerebellum. This channel contains a coupling/regulatory domain, which consists of phosphorylation sites, a proteolytic cleavage region, ATP-binding sites, and binding sites for multiple proteins. This gene is localized to human chromosome 3p26. All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information. Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide Inositol 1,4,5-trisphosphate receptor type 1 recombinant protein epitope signature tag (PrEST) ITPR1 (inositol 1,4,5-trisphosphate receptor, type 1) is a Ca²⁺-channel, which is activated upon binding by inositol 1,4,5-trisphosphate (IP3), and releases Ca²⁺ from endoplasmic reticulum (ER) into the cytoplasm. This released calcium participates in various Ca²⁺-dependent signaling and cellular processes. It is activated on death receptor binding or cellular damage, and regulates intracellular calcium levels during apoptosis. Heterozygous deletion in this gene is responsible for the autosomal dominant neurodegenerative disorder spinocerebellar ataxia type 15 (SCA15), which is characterized by late-onset, slow-progressive cerebellar ataxia. It is involved in the activation of T-cells, where it gets phosphorylated at Y353 residue, located at the IP3-binding domain. It plays an essential role in the initial stages of myoblast differentiation, where it induces the expression of myogenin and MEF2 (myocyte enhancer factor 2), which are transcription factors specific to muscles. ITPR1 is also essential for development and maintenance of cerebellum. Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: •IHC tissue array of 44 normal human tissues and 20 of the most comm
