Many stimuli increase cytoplasmic Ca2+ concentrations as an early signal
transduction event and alter the patterns of nuclear gene transcription,
but the mechanisms by which Ca2+ signals are transduced to the nucleus are
not known. This article shows that at least four DNA binding proteins from
cauliflower nuclear extracts are also calmodulin (CaM) binding proteins.
CaM enhances the binding of these proteins to a C/G-box sequence element in
the Arabidopsis Cam-3 promoter. Binding to the C/G-box is enhanced
preferentially by the CaM isoform encoded by Cam-3. However, it is not
clear whether the effect is mediated directly by CaM or indirectly through
the activity of a CaM-regulated protein phosphatase. CaM also binds
recombinant TGA3 and enhances its binding to the same Cam-3 promoter
element. These results are consistent with the idea that a Ca2+-mediated
signaling pathway eliciting some changes in gene expression may consist of
CaM, or a structurally related Ca2+ binding protein, and transcription
factors.
