CC -!- FUNCTION: Component of the NF-Y/HAP transcription factor complex. The
CC NF-Y complex stimulates the transcription of various genes by
CC recognizing and binding to a CCAAT motif in promoters. May act through
CC association with MADS-box proteins. May regulate the expression of
CC genes involved in flowering. {ECO:0000269|PubMed:11971906}.
CC -!- SUBUNIT: Heterotrimeric transcription factor composed of three
CC components, NF-YA, NF-YB and NF-YC. NF-YB and NF-YC must interact and
CC dimerize for NF-YA association and DNA binding (By similarity).
CC Interacts with MADS18. Forms a ternary complex with the MADS6-MADS18
CC heterodimer. {ECO:0000250, ECO:0000269|PubMed:11971906}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in developing kernels.
CC {ECO:0000269|PubMed:11971906}.
CC -!- MISCELLANEOUS: Probably not a component of a NF-Y/HAP transcription
CC factor complex. Shows impaired association with NF-YA/HAP2 and CAAT
CC motif binding.
CC -!- SIMILARITY: Belongs to the NFYB/HAP3 subunit family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAD12929.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
