Abstract

We found that ionophore A23187 interacted reversibly with calmodulin (CaM), in a calcium-dependent fashion. It was found that A23187 interacts selectively with CaM, among calcium binding proteins (such as troponin C and S-100 protein) and other proteins. However, apparently differing from W-7, A23187 did not suppress CaM-dependent enzyme activity such as myosin light chain kinase and Ca2+-dependent cyclic nucleotide phosphodiesterase. Our observations suggest that there are novel calcium-dependent regions of CaM which can be monitored using ionophore A23187 and may not be related to enzyme activation.
