CC -!- FUNCTION: Probable transcription factor. {ECO:0000250}.
CC -!- INTERACTION:
CC Q8LAT0; Q9SIT9: NFYB7; NbExp=3; IntAct=EBI-4465764, EBI-4459822;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Widely expressed. {ECO:0000269|PubMed:16055682}.
CC -!- DEVELOPMENTAL STAGE: Expressed 3 day after germination (DAG) in first
