Protein function

Encodes a subunit of a CCAAT-binding transcriptional factor.

Phenotype

Multiple mutant:
nf-yb2 and nf-yb3 mutations show additive effects and supress the early flowering of the SUC2:CO transgenic line. [Kumimoto et al., 2008][Hou et al., 2014]

Overexpressor:
NF-YB2 overexpressor is early flowering under LD conditions only. [Kumimoto et al., 2008]

Single mutant:
nf-yb2 single mutant is slighlty late flowering under LD conditions only. [Kumimoto et al., 2008][Hou et al., 2014]

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]
