MBF1 Transcription Factor Family
Multiprotein bridging factor 1 (MBF1) is known to be a transcriptional co-activator
that mediates transcriptional activation by bridging between an activator and a
TATA-box binding protein (TBP). We demonstrated that expression of every three MBF1
from Arabidopsis partially rescues the yeast mbf1 mutant phenotype, indicating that all
of them function as co-activators for GCN4-dependent transcriptional activation. We
also report that each of their subtypes shows distinct tissue-specific expression
patterns and responses to phytohormones. These observations suggest that even though
they share a similar biochemical function, each MBF1 has distinct roles in various
tissues and conditions.
