OBSOLETE. The function of binding to an RNA polymerase (RNAP) transcription regulator and recruiting it to the general transcription machinery complex in order to modulate transcription initiation.

OBSOLETE. The function of binding to an RNA polymerase II (RNAP II) transcription regulator and recruiting it to the general transcription machinery complex in order to modulate transcription initiation.

OBSOLETE. Binding to a member of the class of TATA-binding proteins (TBP), including any of the TBP-related factors (TRFs), in order to modulate transcription. The transcription factor may or may not also interact selectively with DNA as well.

OBSOLETE. Binding to a member of the class of TATA-binding proteins (TBP), including any of the TBP-related factors (TRFs), to facilitate the aggregation, arrangement and bonding together of proteins on RNA polymerase II promoter DNA to form the transcriptional preinitiation complex (PIC), the formation of which is a prerequisite for transcription by RNA polymerase.

OBSOLETE. Binding to an RNA polymerase II (RNAP II) regulatory transcription factor and also with the RNAP II basal transcription machinery in order to increase the frequency, rate or stability of the aggregation, arrangement and bonding together of proteins on RNA polymerase II promoter DNA to form the transcriptional preinitiation complex (PIC). Cofactors generally do not bind DNA, but rather mediate protein-protein interactions between activating transcription factors and the basal RNAP II transcription machinery.

The acquisition, loss, or modification of macromolecules within a protein-DNA complex, resulting in the alteration of an existing complex.

The disaggregation of a transcription ternary complex, composed of RNA polymerase, template DNA, and an RNA transcript, into its constituent components.

The disaggregation of a protein-DNA-RNA complex into its constituent components.

The acquisition, loss, or modification of macromolecules within a protein-DNA-RNA complex, resulting in the alteration of an existing complex.

Any process in which macromolecules aggregate, disaggregate, or are modified, resulting in the formation, disassembly, or alteration of a protein-DNA-RNA complex.
