Transcription factor S-II (TFIIS), central domain; Transcription elongation by RNA polymerase II is regulated by the general elongation factor TFIIS. This factor stimulates RNA polymerase II to transcribe through regions of DNA that promote the formation of stalled ternary complexes. TFIIS is composed of three structural domains, termed I, II, and III. The two C-terminal domains (II and III), this domain and pfam01096 are required for transcription activity.

 233-279 7.31e-28

domain III/zinc ribbon domain of Transcription Factor IIS; TFIIS is a zinc-containing transcription factor. It has been shown in vitro to have distinct biochemical activities, including binding to RNA polymerases, stimulation of transcript elongation, and activation of a nascent RNA cleavage activity in the RNA polymerase II (Pol II) elongation complex. TFIIS consists of three domains. Domain II and III are sufficient for all known TFIIS activities. Domain III is a zinc ribbon that separated from domain II by a long linker and is indispensable for TFIIS function. The TFIIS homologs, subunits A12.2, B9, and C11, of Pol I, II, and III respectively, are required for RNA cleavage by the polymerases. In a single organism, there are tissue-specific TFIIS related proteins.

C-terminal zinc ribbon domain of RNA polymerase intrinsic transcript cleavage subunit; The homologous C-terminal zinc ribbon domains of subunits A12.2, Rpb9, and C11 in RNA Polymerases (Pol) I, II, and III, respectively are required for intrinsic transcript cleavage. TFS is a related archaeal protein that is involved in RNA cleavage by archaeal polymerase. These proteins have two zinc-binding beta-ribbon domains, N-terminal zinc ribbon (N-ribbon) and C-terminal zinc ribbon (C-ribbon). Transcription Factor IIS (TFIIS) domain III is homologous to the C-ribbon domain that stimulates the weak cleavage activity of Rpb9 for Pol II.

C-terminal zinc ribbon domain of RPC11 subunit of RNA polymerase III; The C-terminal zinc ribbon domain (C-ribbon) of subunit C11 (Zn-ribbon_RPC11) in RNA polymerase (Pol) III is required for intrinsic transcript cleavage. RPC11 is also involved in Pol III termination. Eukaryote genomes are transcribed by three nuclear RNA polymerases (Pol I, II and III) that share some subunits. RPC11 has strong homology to RPB9 of Pol II and RPA12 of Pol I. Zn-ribbon_RPC11 is homologous to Pol II elongation factor TFIIS domain III. C11 has two zinc-binding domains separated by a flexible linker.

C-terminal zinc ribbon domain of archaeal Transcription Factor S (TFS); TFS is an archaeal protein that stimulates the intrinsic cleavage activity of archaeal RNA polymerase. TFS C-terminal domain shows sequence similarity to the homologous C-terminal zinc ribbon domain of subunits A12.2, Rpb9, and C11 in eukaryotic RNA Polymerases (Pol) I, II, and III, respectively and domain III of TFIIS. TFS is not a subunit of archaeal RNA polymerase even though its domains arrangement is similar to A12.2, Rpb9, and C1. TFS is a transcription factor with a similar function to eukaryotic TFIIS. TFS has external cleavage induction activity and improves the fidelity of transcription. TFS has two zinc-binding domains.

 10-56 8.65e-09

TFIIS helical bundle-like domain; Mediator is a large complex of up to 33 proteins that is conserved from plants to fungi to humans - the number and representation of individual subunits varying with species {1-2]. It is arranged into four different sections, a core, a head, a tail and a kinase-activity part, and the number of subunits within each of these is what varies with species. Overall, Mediator regulates the transcriptional activity of RNA polymerase II but it would appear that each of the four different sections has a slightly different function. Mediator exists in two major forms in human cells: a smaller form that interacts strongly with pol II and activates transcription, and a large form that does not interact strongly with pol II and does not directly activate transcription. Notably, the 'small' and 'large' Mediator complexes differ in their subunit composition: the Med26 subunit preferentially associates with the small, active complex, whereas cdk8, cyclin C, Med12 and Med13 associate with the large Mediator complex. This family includesthe C terminal region of a number of eukaryotic hypothetical proteins which are homologous to the Saccharomyces cerevisiae protein IWS1. IWS1 is known to be an Pol II transcription elongation factor and interacts with Spt6 and Spt5.

Eukaryote genomes are transcribed by three nuclear RNA polymerases (Pol I, II and III) that share some subunits. RPB9 have strong homology to RPA12 of Pol I and RPC11 of Pol III subunits but its intrinsic cleavage activity is weaker for Pol II. Zn-ribbon_RPB9 is homologous to Pol II elongation factor TFIIS domain III. The very weak cleavage activity of Pol II is stimulated by TFIIS. RPB9 has two zinc-binding domains separated by a flexible linker.

transcription factor S, archaeal; This model describes archaeal transcription factor S, a protein related in size and sequence to certain eukaryotic RNA polymerase small subunits, and in sequence and function to the much larger eukaryotic transcription factor IIS (TFIIS). Although originally suggested to be a subunit of the archaeal RNA polymerase, it elutes separately from active polymerase in gel filtration experiments and acts, like TFIIs, as an induction factor for RNA cleavage by RNA polymerase. There has been an apparent duplication event in the Halobacteriaceae lineage (Haloarcula, Haloferax, Haloquadratum, Halobacterium and Natromonas). There appears to be a separate duplication in Methanosphaera stadtmanae. [Transcription, Transcription factors]
