The inositol (1,4,5)-trisphosphate receptor (InsP3R) regulates calcium release from storage within cells and plays an important role in neuronal function. InsP3R has been linked to Huntington’s disease. InsP3R has also been linked to the association between cAMP and Ca2+ signaling in regions of the brain, including the neostriatum.
特異性
This antibody recognizes InsP3R at the cytoplasmic domain.
免疫原
KLH-conjugated linear peptide corresponding to the cytoplasmic domain of rat InsP3R.
應用
Immunohistochemistry Analysis: 1:1500 dilution from a previous lot detected InsP3R in purkinje cells at the junction of the granular and molecular layers of normal rat cerebellum tissue.
Immunoprecipitation Analysis: 10 µg of Anti-InsP3R, Type 1 immunoprecipitated InsP3R, Type 1 from rat brain microsomal prep RIPA lysate.

Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominantly inherited neurodegenerative disorder with preferential affection of Purkinje neurons, which are known as integrators of calcium currents. The expansion of a polyglutamine (polyQ) domain in the RNA-binding protein ataxin-2 (ATXN2) is
Spontaneous Ca2+ signaling from the InsP3R intracellular Ca2+ release channel to mitochondria is essential for optimal oxidative phosphorylation (OXPHOS) and ATP production. In cells with defective OXPHOS, reductive carboxylation replaces oxidative metabolism to maintain amounts of reducing equivalents and metabolic
