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 regulate the
CC expression of photosynthetic genes, and may be involved in chloroplast
CC and amyloplast development. {ECO:0000269|PubMed:14617083}.
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 NFYC4 and NFYC6 (PubMed:18193457). {ECO:0000250,
CC ECO:0000269|PubMed:18193457}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Ubiquitous. {ECO:0000269|PubMed:14617083}.
CC -!- SIMILARITY: Belongs to the NFYB/HAP3 subunit family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAH91366.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
