-  At the time of obsoletion, under "regulation of molecular function", a term exists for "regulation of sequence-specific DNA binding transcription factor activity" and the positive and negative child terms, but no more detailed terms exist. In reannotating, please consider if the paper would support annotation to a regulation term for a specific RNA polymerase. Also consider if what you need would be regulation of protein binding transcription factor activity or any of its child terms instead. If so, please consider making a SF item regarding creation of such a term.
