TAP Subfamily: NF-YB
Bernadt et al (2005): NF-Y is a bifunctional transcription factor capable of activating or repressing transcription. NF-Y specifically recognizes CCAAT box motifs present in many eukaryotic promoters. The mechanisms involved in regulating its activity are poorly understood.
This TAP family belongs to the Heteromeric CCAAT-binding factors structural class of the Other all-alpha-helical DNA-binding domains structural superclass, as defined in Plant-TFClass (Blanc-Mathieu et al. 2024)
