RT "A tobacco bZip transcription activator (TAF-1) binds to a G-box-like motif
RT conserved in plant genes.";
RL EMBO J. 10:1793-1802(1991).
CC -!- FUNCTION: Trans-activator of a beta-glucuronidase (GUS) reporter gene.
CC Binds to a G-box-related element, (5'-GCAACGTGGC-3'). Also binds to the
CC HEX-motif of wheat histone H3 promoter.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- TISSUE SPECIFICITY: Present mainly in roots. Barely detectable in stems
CC and leaves.
CC -!- SIMILARITY: Belongs to the bZIP family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA42915.1; Type=Erroneous initiation; Evidence={ECO:0000305};
