obsolete regulation of transcription regulator activity true OBSOLETE. Any process that modulates the frequency, rate or extent of transcription regulator activity, any molecular function that plays a role in regulating transcription; may bind a promoter or enhancer DNA sequence or interact with a DNA-binding transcription factor. 2009-08-07T10:19:57Z 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. regulation of transcription regulator activity GO:0090046 tb biological_process
