摘要
Inositol 1,4,5-trisphosphate receptors (InsP(3)R) are a family of ubiquitously expressed intracellular Ca2+ channels. Isoform-specific properties of the three family members may play a prominent role in defining the rich diversity of the spatial and temporal characteristics of intracellular Ca2+ signals. Studying the properties of the particular family members is complicated because individual receptor isoforms are typically never expressed in isolation. In this article, we discuss strategies for studying Ca2+ release through individual InsP(3)R family members with particular reference to methods applicable following expression of recombinant InsP(3)R and mutant constructs in the DT40-3KO cell line, an unambiguously null InsP(3)R expression system.
