CC   -!- FUNCTION: Component of the sequence-specific heterotrimeric
CC       transcription factor (NF-Y) which specifically recognizes a 5'-CCAAT-3'
CC       box motif found in the promoters of its target genes. NF-Y can function
CC       as both an activator and a repressor, depending on its interacting
CC       cofactors. {ECO:0000256|ARBA:ARBA00025263}.
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. Interacts with C1QBP.
CC       {ECO:0000256|ARBA:ARBA00025891}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123}.
CC   -!- SIMILARITY: Belongs to the NFYB/HAP3 subunit family.
CC       {ECO:0000256|ARBA:ARBA00009053}.
