Popis:	Multiprotein bridging factor 1 (MBF1) is a transcriptional coactivator. It has been reported that MBF1 changed its subcellular localization from cytoplasm into nuclei with a transcriptional activator for activation of a target gene expression in animals. We found that Arabidopsis MBF1s (AtMBF1s) predominantly localize in nucleolus. We previously reported that plant MBF1s were rapidly induced by several stresses, whereas animal MBF1s were not induced. Therefore, we suggest that MBF1-function in plants is controlled on the level of transcriptional induction but not by nuclear translocation, dissimilar from the case of MBF1s from animals.
