The recently identified cyclic nucleotide-gated ion channels (AtCNGCs) from Arabidopsis thaliana have the ability to bind calmodulin. Using two different methods, we mapped the binding site of AtCNGC1 to the last predicted alpha helix of the cyclic nucleotide binding domain. This is in contrast to CNGCs from animals, where the calmodulin binding site is located in the N-terminus, implying that different mechanisms for CNGC modulation have evolved in animals and plants. Furthermore, we… CONTINUE READING
