Description
Product Usage Information
Western Blotting: 1:1000
Immunoprecipitation: 1:50
Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at -20°C. Do not aliquot the antibody.
Protocol
Available protocols: Western Blotting, Immunoprecipitation
Specificity / Sensitivity
Phospho-IP3 Receptor (Ser1756) (D10E3) Rabbit Monoclonal Antibody detects endogenous levels of IP3 receptor only when phosphorylated at Ser1756.
Species Reactivity: Human, Mouse, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser1764 of human IP3 receptor protein. This site is equivalent to Ser1756 in the rat IP3 receptor sequence.
Background
Inositol 1,4,5-triphosphate receptor, also known as IP3R or InsP3R, is a member of the intracellular calcium release channel family and is located in the endoplasmic reticulum. IP3R functions as a Ca release channel for intracellular stores of calcium ions. There are three types of IP3 receptors (IP3R1, 2, and 3) that require the second messenger inositol 1,4,5-triphosphate (IP3) for activation (1). Four individual subunits homo- or hetero-oligomerize to form the receptor's functional channel (2). Phosphorylation of IP3R1 at Ser1756 by cyclic AMP-dependent protein kinase A (PKA) regulates the sensitivity of IP3R1 to IP3 and may be a mode of regulation for Ca release (3,4). IP3R1-mediated Ca release appears to have an effect on the induction of long term depression (LTD) in Purkinje cells (5).
