英文摘要
We measured activity of L-type Ca^<2+> channel and its mutants, C-terminal deletion (delta CT) and delta CT linked with calmodulin (CaM), using patch-clamp technique (inside-out mode). We found that binding of CaM to the channel was required for the channel activity. Unlike the wild type channel, the mutants did not require ATP for the channel activity. It was suggested that CaM and ATP interacted with a proximal part of C-terminal thereby producing the channel activity, which was modulated negatively by a distal part of C-terminal.
