Usage guidance: Most DNA-binding transcription factors do not have enzymatic activity. The presence of specific DNA-binding domains known to be present in DNA-binding transcription factors (HOX, GATA etc) should be used to help decide whether a protein is a DNA binding transcription factor or a coregulator. If a protein has an enzymatic activity (for example, ubiquitin ligase, histone acetyl transferase) and no known DNA binding domain, consider annotating to GO:0003712 transcription coregulator activity. Special care should be taken with proteins containing zinc fingers, Myb/SANT and ARID domains, since only a subset of proteins containing these domains directly and selectively bind to regulatory DNA motifs in cis-regulatory regions.
