CC -!- FUNCTION: Transcription factor probably involved in vascular
CC development and shoot tissue organization. Binds to the DNA sequence
CC 5'-CCGAGTGTGCCCCTGG-3' present in the promoter region Box II of the
CC phloem-specific rice tungro bacilliform virus (RTBV) promoter. May
CC regulate tissue-specific expression of the RTBV promoter and virus
CC replication. {ECO:0000269|PubMed:14704272}.
CC -!- SUBUNIT: Binds DNA as a homodimer or as a heterodimer with RF2a. The
CC heterodimer binds stronger to DNA than the homodimer.
CC {ECO:0000269|PubMed:14704272}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00978,
CC ECO:0000269|PubMed:14704272}.
CC -!- TISSUE SPECIFICITY: Expressed at high levels in roots, low level in
CC leaf sheath, but not in leaf blade. Predominantly expressed in vascular
CC tissues. {ECO:0000269|PubMed:14704272}.
CC -!- SIMILARITY: Belongs to the bZIP family. {ECO:0000305}.
