General Information
Term inositol 1,4,5-trisphosphate-gated calcium channel activity ID (Ontology) GO:0005220 (Gene Ontology)
Definition Enables the transmembrane transfer of a calcium ion by a channel that opens when inositol 1,4,5-trisphosphate (IP3) has been bound by the channel complex or one of its constituent parts.[ PubMed:28416699 PubMed:8660280 ]
Also Known As "inositol 1,4,5-trisphosphate-sensitive calcium-release channel activity" ; "inositol-1,4,5-trisphosphate receptor activity" ; "InsP3 receptor" (for all, see Synonyms field below)
