CC   -!- FUNCTION: Involved in the abaxial cell fate determination during
CC       embryogenesis and organogenesis. {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with SPL/NZZ and SPEAR2 (PubMed:25527103).
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed at low levels in abaxial regions of
CC       lateral aerial organ primordia leading to cotyledons, leaves, flower
CC       meristems, sepals, petals, stamen and carpels, but not in roots.
CC       {ECO:0000269|PubMed:10457020}.
CC   -!- DEVELOPMENTAL STAGE: Expressed in subepidermal cells of anlagen
CC       regions, then in abaxial part of primordia and finally in
CC       differentiating organs. Levels decrease in differentiated organs. In
CC       embryo, expressed from the heart stage in the abaxial domain of the
CC       cotyledon primordia and decrease as the embryo matures. In stamen,
CC       expression restricted to the abaxial region differentiating into the
CC       connective. In gynoecium, expressed in the abaxial cell layers
CC       differentiating into the valves. {ECO:0000269|PubMed:10457020}.
CC   -!- SIMILARITY: Belongs to the YABBY family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAF22893.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
