Description

In most species, Nuclear Factor Y (NF-Y) transcription factors are present. They usually composed three subunits: NF-YA/HAP2, NF-YB/HAP3, and NF-YC/HAP5. This group of TF has been implicated in diverse developmental process from animal to plant.
Plant NF-YB proteins have variable in length (e.g., 90?C240 amino acids in M. truncatula). They are characterized by a central domain that has structural and amino acid similarity with the histone fold motif (HFM) of the core histone H2B. This motif is composed of three alpha-helices separated by two beta strand-loop domains. It is involved in both protein?C DNA and protein?Cprotein interactions.
