Dof Transcription Factor Family
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.
Notes: Dof is missed in PlnTFDB, and AtPID.
