Term Detail
GO term:transcription cofactor activity
Synonym: transcriptional cofactor activity
Synonym: transcriptional co-regulator
Synonym: transcription cofactor activity
GO id:GO:0003712
Definition:Interacting selectively and non-covalently with a regulatory transcription factor and also with the basal transcription machinery in order to modulate transcription. Cofactors generally do not bind the template nucleic acid, but rather mediate protein-protein interactions between regulatory transcription factors and the basal transcription machinery.
