We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

'''Transcriptional activators''' (TA) are proteins which bind to DNA and stimulate nearby gene transcription. TA transcription stimulation is achieved by enhancing RNA polymerase binding or by enhancing the formation of open complex which is required for initiation of transcription. TA bind to a specific DNA sequence in or near an operon via their DNA-binding domain (DBD). TA contains 3 domains: DBD, trans-activating domain (TAD) which binds coregulator proteins and an optional ligand-binding domain (LBD) which sense external signals.
