ITPR3 encodes IP3R3, an endoplasmic reticulum-localized inositol 1,4,5-trisphosphate-gated Ca2+ release channel that converts IP3-coupled receptor signaling into cytosolic and mitochondrial Ca2+ flux (PMID:8388391, PMID:28614305). A dominant function of IP3R3 is to deliver Ca2+ from the ER to mitochondria at ER-mitochondria contact sites (MAMs), where it is recruited and tethered through interactions with TOM70, GRP75/VDAC1, Sigma-1 receptor, and Mfn2 to sustain oxidative phosphorylation and, under overload, to drive apoptosis (PMID:29395920, PMID:32916960, PMID:40128893, PMID:40595218). The abundance of IP3R3 is set by a ubiquitin-proteasome axis: the SCF F-box protein FBXL2 binds IP3R3 and targets it for p97- and proteasome-dependent degradation, a reaction antagonized by PTEN (which competes for IP3R3 binding) and by FUNDC1 (which stabilizes FBXL2), and opposed by the ER-localized deubiquitylase BAP1, which removes ubiquitin to stabilize IP3R3 and license genotoxic-stress apoptosis (PMID:28614305, PMID:28614300, PMID:32938669). Through this Ca2+-apoptosis and Ca2+-bioenergetic output, IP3R3 acts as a context-dependent determinant of cell fate, influencing chemotherapy-induced apoptosis, cancer cell survival, invasion and metabolism via NF-κB/RELB, CD44, and cytoskeletal RhoA signaling (PMID:29630900, PMID:34518526, PMID:33573671, PMID:35487218). Its expression is tuned transcriptionally and epigenetically, by KLF4/H3K27ac under pulsatile shear stress in endothelial cells and by SMARCA4/2-dependent chromatin accessibility (PMID:30917677, PMID:34518526). IP3R3-dependent ER Ca2+ release is also required to trigger store-operated Ca2+ entry for NF-κB/NFAT-driven T cell activation, and dominant de novo ITPR3 variants (recurrent p.Arg2524Cys) act through a dominant-negative mechanism to cause a multisystemic disorder comprising combined immunodeficiency, Charcot-Marie-Tooth neuropathy, and ectodermal dysplasia (PMID:39560673, PMID:39270020). In specialized sensory tissue, IP3R3 is specifically required for GPCR-coupled taste transduction (PMID:23859941).
