IP3R3 Small Molecules and Peptides

IP3R3 (inositol 1,4,5-triphosphate receptor type 3) is an intracellular calcium release channel that mediates calcium release from the endoplasmic reticulum. There are 3 mammalian IP3R receptors: IP3R1, IP3R2, and IP3R3. IP3R3 has been shown to play a role in olfactory mucus secretion and in the taste perception of sweet, savory (umami), and bitter substances.
