Function

Inositol 1,4,5-trisphosphate-gated calcium channel that, upon inositol 1,4,5-trisphosphate binding, mediates calcium release from the endoplasmic reticulum (ER) (PubMed:10620513, PubMed:27108797). Undergoes conformational changes upon ligand binding, suggesting structural flexibility that allows the channel to switch from a closed state, capable of interacting with its ligands such as 1,4,5-trisphosphate and calcium, to an open state, capable of transferring calcium ions across the ER membrane (By similarity). Cytoplasmic calcium released from the ER triggers apoptosis by the activation of CAMK2 complex (By similarity). Involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1 (By similarity). Part of a complex composed of HSPA9, ITPR1 and VDAC1 that regulates mitochondrial calcium-dependent apoptosis by facilitating calcium transport from the ER lumen to the mitochondria intermembrane space thus providing calcium for the downstream calcium channel MCU that directly releases it into mitochondria matrix (By similarity). Regulates fertilization and egg activation by tuning the frequency and amplitude of calcium oscillations (By similarity).

Activity summary

The IP3 receptor (IP3R) also known as inositol 145-trisphosphate receptor functions as a ligand-gated calcium channel. It plays a major role in calcium release from the endoplasmic reticulum into the cytoplasm. The IP3 receptor has a molecular mass of approximately 313 kDa. IP3 receptor expression is extensive found in various tissues including the brain liver and smooth muscle cells. It is an essential component of intracellular calcium signaling mechanisms directly activated by IP3 a secondary messenger molecule.

Biological function summary

IP3 receptor involves in various cellular processes by mediating intracellular calcium release. Upon binding of IP3 produced by phospholipase C catalysis of PIP2 the channel opens to allow calcium ions to flow into the cytosol. The IP3 receptor forms a tetrameric complex essential for its function. This complex is vital for responses in signal transduction pathways affecting T-cell activation muscle contraction and neurotransmitter release.

Pathways

IP3 receptor is central to calcium signaling and interacts with the IP3 pathway modulating cellular activities in response to different stimuli. The interaction with proteins such as TRPC3 a transient receptor potential channel integrates calcium influx. IP3 receptor also participates in the calcium/calmodulin-dependent protein kinase (CaMK) pathway impacting phosphorylation events in the cell.

Associated diseases and disorders

Dysregulation of IP3 receptor function associates with neurodegenerative diseases such as Alzheimer's Disease due to calcium homeostasis disruption. The receptor also connects to heart diseases where abnormal calcium signaling can lead to arrhythmic conditions. The interaction between the IP3 receptor and other proteins like ryanodine receptors may exacerbate these conditions influencing cellular calcium dynamics in pathological states.
