Source	Description
UniProt	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. May act through association with MADS-box proteins. May regulate the expression of genes involved in flowering. {ECO:0000269\|PubMed:11971906}.

Results suggested that the endosperm-specific gene OsNF-YB1/OsHAP3K (AJ300218) might be a cell cycle regulator and played a role in maintaining the endosperm cell proliferation. [PMID: 25178525] the aleurone-specific NF-YB1 plays an important role in regulating rice grain filling through activating the expression of SUT1, SUT3 and SUT4. [PMID: 26403192] aleurone layer specific, regulates grain filling and endosperm development by interacting with an ERF transcription factor [PMID: 27803124]
