Protein function

Encodes a subunit of a CCAAT-binding transcriptional factor.

Phenotype

Remarks:
NF-YB1 overexpressing lines have reduced FT expression levels. [Wenkel et al., 2006]

Overexpressor:
NF-YB1 overexpressor is late flowering under LD conditions only. (The late flowering-time phenotype is stronger in Ler than Col-0 background. ) [Wenkel et al., 2006]

Function:
Component of the NF-Y/HAP transcription factor complex. The NF-Y complex stimulates the transcription of various genes by recognizing and binding to a CCAAT motif in promoters. [Data from UniProt]
