TAP Family: C2C2_Dof
Yanagisawa (2004): Dof (DNA-binding with one finger) domain proteins are plant-specific transcription factors with a highly conserved DNA-binding domain, which presumably includes a single C(2)-C(2) zinc finger. During the past decade, numerous Dof domain proteins have been identified in both monocots and dicots including maize, barley, wheat, rice, tobacco, Arabidopsis, pumpkin, potato, and pea. Biochemical, molecular biological and molecular genetic analyses revealed that Dof domain proteins function as a transcriptional activator or a repressor involved in diverse plant-specific biological processes. Although more physiological roles of Dof domain proteins would be elucidated in future because of numerous Dof domain proteins in plants, it is already evident that the Dof domain proteins play critical roles as transcriptional regulators in plant growth and development.
This TAP family belongs to the Other C4 zinc finger-type factors structural class of the Zinc-coordinating DNA-binding domains structural superclass, as defined in Plant-TFClass (Blanc-Mathieu et al. 2024)
