Protein: Inositol 1,4,5-trisphosphate-gated calcium channel ITPR3 (IP3 receptor isoform 3) (IP3R-3) (InsP3R3) (Type 3 inositol 1,4,5-trisphosphate receptor) (Type 3 InsP3 receptor) (Q14573)
Organism: Homo sapiens (Human)
Function: Receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium.
Subcellular location: Endoplasmic reticulum membrane {ECO:0000250|UniProtKB:Q63269}; Multi-pass membrane protein {ECO:0000255}.
