CC -!- FUNCTION: RECEPTOR FOR INOSITOL 1,4,5-TRISPHOSPHATE, A SECOND CC MESSENGER THAT MEDIATES THE RELEASE OF INTRACELLULAR CALCIUM. CC -!- SUBUNIT: Homotetramer. CC -!- SUBCELLULAR LOCATION: Integral membrane protein. Endoplasmic CC reticulum. CC -!- ALTERNATIVE PRODUCTS: 8 isoforms; 1/SISIIABC (shown here), 2/SI- CC SIIABC, 3/SISIIAC, 4/SI-SIIAC, 5/SISIIA, 6/SI-SIIA, 7/SISII and CC 8/SI-SII; may be produced by alternative splicing. There is a CC combination of two alternatively spliced domains at site SI and CC site SII (A, B and C). CC -!- DOMAIN: THE RECEPTOR CONTAINS A CALCIUM CHANNEL IN ITS C-TERMINAL CC EXTREMITY. ITS LARGE N-TERMINAL CYTOPLASMIC REGION HAS THE LIGAND- CC BINDING SITE IN THE N-TERMINUS AND MODULATORY SITES IN THE MIDDLE CC PORTION IMMEDIATELY UPSTREAM OF THE CHANNEL REGION. CC -!- PTM: PHOSPHORYLATED BY CYCLIC-AMP KINASE. PHOSPHORYLATION PREVENTS CC THE LIGAND-INDUCED OPENING OF THE CALCIUM CHANNELS. CC -!- PTM: PHOSPHORYLATED ON TYROSINE RESIDUES (BY SIMILARITY). CC -!- MISCELLANEOUS: CALCIUM APPEARS TO INHIBIT LIGAND BINDING TO THE CC RECEPTOR, MOST PROBABLY BY INTERACTING WITH A DISTINCT CC CALCIUM-BINDING PROTEIN WHICH THEN INHIBITS THE RECEPTOR. CC -!- SIMILARITY: BELONGS TO THE INSP3 RECEPTOR FAMILY.
