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. Plays a role in the regulation of the embryogenesis. Involved in the abscisic acid (ABA) signaling pathway. {ECO:0000269\|PubMed:12509518, ECO:0000269\|PubMed:17322342}.
