Source Description
TAIREncodes a subunit of CCAAT-binding complex, binds to CCAAT box motif present in some plant promoter sequences. One of three members of this class (HAP2A, HAP2B, HAP2C), it is expressed in vegetative and reproductive tissues.
UniProtStimulates the transcription of various genes by recognizing and binding to a CCAAT motif in promoters. {ECO:0000250}.
Function -- GeneRIF ? help Back to Top
  1. The miR169 family regulates stress-induced flowering by repressing the AtNF-YA transcription factor, which in turn reduces the expression of FLOWERING LOCUS C (FLC), allowing for the expression of FLC target genes
    [PMID: 24336445]
  2. The authors identified a regulatory node involving the particular miR169defg isoform and NF-YA2 and NF-YA10 genes that acts in the control of primary root growth.
    [PMID: 24533947]
  3. Findings showed leaf development was regulated by NF-YA2 and NF-YA10 through the auxin-signaling pathway and may provide a new insight into the genetic engineering of vegetables biomass and crop productivity.
