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.
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       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the NFYB/HAP3 subunit family. {ECO:0000305}.
