RT "A maize zinc-finger protein binds the prolamin box in zein gene promoters
RT and interacts with the basic leucine zipper transcriptional activator
RT Opaque-2.";
RL Proc. Natl. Acad. Sci. U.S.A. 94:7685-7690(1997).
CC -!- FUNCTION: Transcription factor that binds specifically to a 5'-AA[AG]G-
CC 3' consensus core sequence. May enhance the DNA binding of the bZIP
CC transcription factor Opaque-2 to O2 binding site elements.
CC -!- SUBUNIT: Interacts with the bZIP transcription factor Opaque-2/O2.
CC {ECO:0000269|PubMed:9207153}.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- TISSUE SPECIFICITY: Seed endosperm. {ECO:0000269|PubMed:9207153}.
