Term Name: inositol 1,4,5-trisphosphate-gated calcium channel activity
Synonyms: inositol 1,4,5-trisphosphate-sensitive calcium-release channel activity, inositol-1,4,5-trisphosphate receptor activity, InsP3 receptor, IP3 receptor activity
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.
