FunctionIntracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate.
Tissue specificityWidely expressed.
Involvement in diseaseDefects in ITPR1 are the cause of spinocerebellar ataxia type 15 (SCA15) (SCA15) [MIM:606658]. Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA15 is an autosomal dominant cerebellar ataxia (ADCA). It is very slow progressing form with a wide range of onset, ranging from childhood to adult. Most patients remain ambulatory.
Sequence similaritiesBelongs to the InsP3 receptor family.
Contains 5 MIR domains.
DomainThe 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.
modificationsPhosphorylated by cAMP kinase. Phosphorylation prevents the ligand-induced opening of the calcium channels.
Phosphorylated on tyrosine residues.
Cellular localizationEndoplasmic reticulum membrane.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: IP3 receptor knockout HAP1 cell lysate (20 µg)
Lane 3: Human brain tissue lysate (20 µg)
Lane 4: SH-SY5Y cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab125076 observed at 270 kDa. Red - loading control, ab18058, observed at 124 kDa.
ab125076 was shown to specifically recognize IP3 receptor in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when IP3 receptor knockout samples were examined. Wild-type and IP3 receptor knockout samples were subjected to SDS-PAGE. ab125076 and ab18058 (loading control to Vinculin) were diluted 1/1000 and 1/10,000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.
