Protein: Inositol 1,4,5-trisphosphate receptor (InsP3 receptor) (IP3R) (InsP3R) (P29993)
Organism: Drosophila melanogaster (Fruit fly)
Function: Receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. Together with MCU, has a role in oxidative stress-induced ER-mitochondria calcium transfer. May be involved in visual and olfactory transduction, and myoblast proliferation. May be involved in ethanol tolerance.
Subcellular location: Endoplasmic reticulum membrane; Multi-pass membrane protein.
Interaction partners:
- Stromal interaction molecule homolog
- Voltage-dependent anion-selective channel
- Calcium release-activated calcium channel protein 1
- Calcium-transporting ATPase sarcoplasmic/endoplasmic reticulum type
- Beclin-1-like protein
- Calmodulin
- Calcium-binding protein E63-1
- EF-hand domain-containing protein
- AT10229p
- GEO12020p1
