Method: Electron Microscopy, Resolution 3.32Å Ligands: PLX, ZN Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function ITPR2_MOUSE Inositol 1,4,5-trisphosphate-gated calcium channel that upon inositol 1,4,5-trisphosphate binding transports calcium from the endoplasmic reticulum lumen to cytoplasm (PubMed:15632133, PubMed:19608738, PubMed:20189985, PubMed:22547632, PubMed:25329695). Exists in two states; a long-lived closed state where the channel is essentially 'parked' with only very rare visits to an open state and that ligands facilitate the transition from the 'parked' state into a 'drive' mode represented by periods of bursting activity (PubMed:22547632). Has neither inositol 1,4,5-trisphosphate binding activity nor calcium releasing activity.
