STRUCTURE OF THE CONSERVED DOMAIN OF ANAC, A MEMBER OF THE NAC FAMILY OF TRANSCRIPTION FACTORS
Overview
The structure of the DNA-binding NAC domain of Arabidopsis ANAC, (abscisic-acid-responsive NAC) has been determined by X-ray, crystallography to 1.9A resolution (Protein Data Bank codes 1UT4 and, 1UT7). This is the first structure determined for a member of the NAC, family of plant-specific transcriptional regulators. NAC proteins are, characterized by their conserved N-terminal NAC domains that can bind both, DNA and other proteins. NAC proteins are involved in developmental, processes, including formation of the shoot apical meristem, floral organs, and lateral shoots, as well as in plant hormonal control and defence. The, NAC domain does not possess a classical helix-turn-helix motif; instead it, reveals a new transcription factor fold consisting of a twisted beta-sheet, surrounded by ... [(full description)]
