ZIM Transcription Factor Family
This short motif is found in a variety of plant transcription factors that contain GATA domains as well as other motifs. The
most conserved amino acids form the pattern TIFF/YXG. This domain may be involved in binding DNA. The ZIM family gene is
that contains ZIM motif but no belong to GATA family.
The deduced protein has a modular structure with a putative single C2-C2 zinc-finger motif distantly related to a
GATA-1-type finger, a basic region with a sequence resembling a nuclear localization signal, and an acidic region. The gene
seemed to have been formed by the exon-shuffling during its molecular evolution, since individual domains are encoded by
discrete exons. RNA gel blot analysis showed its expression in shoot apex and flowers in the reproductive phase. The gene
was named ZIM for Zinc-finger protein expressed in Inflorescence Meristem. The nuclear localization of ZIM was detected
using GFP as a reporter. These results suggest that ZIM is a putative transcription factor involved in inflorescence and
flower development.
By differential screening of an arrayed normalized cDNA library from the inflorescence apex in Arabidopsis, a cDNA clone
having a deduced amino acid sequence with a motif for a zinc finger was isolated as one of the genes expressed specifically
in the reproductive phase. The deduced protein has a modular structure with a putative single C2-C2 zinc-finger motif
