Isolation of a Calmodulin-binding Transcription Factor from Rice (Oryza sativa L.)

Calmodulin (CaM) regulates diverse cellular functions by modulating the activities of a variety of enzymes and proteins. However, direct modulation of transcription factors by CaM has been poorly understood. In this study, we isolated a putative transcription factor by screening a rice cDNA expression library by using CaM:horse-radish peroxidase as a probe. This factor, which we have designated transcription has and a a a putative and putative using a and we has of and a the of we a This the and and this and expression by a of of putative of a and a the the by by a CaM a transcription by Calmodulin (CaM) regulates diverse cellular functions by modulating the activities of a variety of enzymes and proteins.
