Abstract

SPA, which we have already applied to characterise IP3 binding to purified IP3 receptors, will be combined with stop-quench methods to examine the rapid kinetics of IP3 binding. Antipeptide antibodies will be used to attach IP3 receptor subtypes to SPA beads to allow their binding characteristics to be determined. The binding of small messengers (ATP, NADH, Ca2+), pharmacological agents (e.g. fura 2) and proteins (e.g. calmodulin) to pure IP3 receptors will be characterised and relevant interactions between them examined. We aim also to assess the practicability of applying SPA methods to other aspects of Ca2+ signalling pathways: the effects of Ca2+ antagonists on 5-HT3 receptors, the interactions of ligands with ryanodine receptors, and receptor-G-protein interactions.
