品种反应性 主要应用 宿主 格式 抗体类型 Ca, B, H, M, Po, Rb, R ELISA, WB Rb Purified Polyclonal Antibody 描述 产品目录编号 07-1210 Replaces AB1622 描述 Anti-IP3 Receptor Antibody Alternate Names - Inositol 1,4,5-Trisphosphate Receptor
背景信息 The InsP3 (inositol 1,4,5-trisphosphate) Receptor family are intracellular Ca2+ channels activated by the second messenger InsP3. There are at least three types of receptor, with distinct tissue-specific expression profiles and subcellular localizations; it is thought that the exact subtype profile conveys precise Ca2+ release responses. Release of Ca2+ from intracellular stores is the trigger for many cellular responses, including muscle contraction. Receptor activity is subject to feedback regulation by Ca2+ concentration, as high cytosolic Ca2+ concentrations shut down the channel. Ca2+ release is augmented by phosphorylation of the Receptor by PKA and PKG. 产品信息 格式 Purified 控制 - RAW264 cell lysate
演示 Purified rabbit polyclonal IgG in buffer containing 10 mM sodium phosphate, 150 mM NaCl, and 0.01% sodium azide, pH 7.5. 应用 应用 This Anti-IP3 Receptor Antibody is validated for use in WB, IF, IH(P), ELISA, IP, RIA for the detection of IP3 Receptor. 主要应用 - ELISA
- Western Blotting
应用说明 Immunohistochemisty (paraffin): IP3 Receptor staining in rat cerebellum, tissue was pretreated with citrate buffer, pH 6.0. A previous lot of this antibody was diluted to 1:100, using IHC-Select® detection with HRP-DAB.
Immunofluorescence: 1:20 - 1:200 dilution from a previous lot. Light fixation, 2% PFA, 90% ethanol fixation; Visualization by confocal microscopy is required, as detection by standard fluorescent microscopy will not be adequate to detect the IP3R. Due to the intensity of confocal lasers, use of an anti-fading agent, such as DABCO, is strongly recommended.
ELISA: 1:2,000 dilution of a previous was used in ELISA.
Immunoprecipitation: 1:200 dilution of a previous lot was used in Immunoprecipitation.
Flow cytometry: 1:1,000 dilution of a previous lot was used in Flow Cytometry.
Radioimmunoassay: 1:10,000 dilution of a previous lot was used in Radioimmunoassay.
Optimal working dilutions must be determined by the end user.
生物信息 免疫原品种 Synthetic peptide (KDSTEYTGPESYV) corresponding to the C-terminus of human IP3 Receptor type 1.
表位 C-terminus 浓缩 Please refer to the Certificate of Analysis for the lot-specific concentration. 宿主 Rabbit 特异性 Reacts with the C-terminal cytoplasmic domain of IP3 receptors Type 1, 2, and 3. IP3 receptors have been shown to play an important role in the regulation of Ca2+ release from internal storage sites during cell activation. AB1622 reacts with IP3 receptor (MW approx. 260 kDa) isolated from a variety of cell types (e.g. lymphocytes, macrophages, granulocytes, fibroblasts, epithelial, endothelial cells, skeletal muscle, cardiac muscle and brain tissues). 同种型 IgG 品种反应性 CanineBovineHumanMousePigRabbitRat Species Reactivity Note Reacts with Bovine, Human, Mouse, Porcine (Pig), Rabbit, Rat and Canine (Dog).

纯化方法 Purified UniProt编号 - Q14643
UniProt汇总 FUNCTION: SwissProt: Q14643 # Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5- trisphosphate.
SIZE: 2758 amino acids; 313945 Da
SUBUNIT: Homotetramer. Interacts with TRPC4. The PPXXF motif binds HOM1, HOM2 and HOM3. Interacts with RYR1, RYR2, ITPR1, SHANK1 and SHANK3. Interacts with TXNDC4 in a pH-, redox state- and calcium- dependent manner which results in the inhibition the calcium channel activity. The strength of this interaction inversely correlates with calcium concentration. Part of cGMP kinase signaling complex at least composed of ACTA2/alpha-actin, CNN1/calponin H1, PLN/phospholamban, PRKG1 and ITPR1. Interacts with AHCYL1 (By similarity). Interacts with MRVI1.
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Widely expressed.
DOMAIN: SwissProt: Q14643 The receptor contains a calcium channel in its C-terminal extremity. Its large N-terminal cytoplasmic region has the ligand- binding site in the N-terminus and modulatory sites in the middle portion immediately upstream of the channel region.
PTM: Phosphorylated by cAMP kinase. Phosphorylation prevents the ligand-induced opening of the calcium channels (By similarity). & Phosphorylated on tyrosine residues.
DISEASE: SwissProt: Q14643 # Defects in ITPR1 are the cause of spinocerebellar ataxia type 15 (SCA15) (SCA15) [MIM:606658]. Spinocerebellar ataxia is a clinically and genetically heterogeneous group of autosomal dominant cerebellar ataxias (ADCA). Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements. Spinocerebellar ataxia is caused by degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA15 is a very slow progressing form. It has a wide range of onset from childhood to adult. Most patients remain ambulatory.
SIMILARITY: Belongs to the InsP3 receptor family. & Contains 5 MIR domains.
MISCELLANEOUS: Calcium appears to inhibit ligand binding to the receptor, most probably by interacting with a distinct calcium- binding protein which then inhibits the receptor产品使用声明 质量保证 Routinely evaluated by Western Blot on RAW 264 lysates.
Western Blot Analysis:
1:500-1,000 dilution of this lot detected IP3 Receptor on 10 μg of RAW 264 lysates.使用声明 - Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
