Function

[TFS2_YEAST] Necessary for efficient RNA polymerase II transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by S-II allows the resumption of elongation from the new 3'-terminus. Can promote the transfer of one strand of a double-stranded DNA molecule to a homologous single strand and thus may be involved in recombination.

Publication Abstract from PubMed

TFIIS is a transcription elongation factor that consists of three domains. We have previously solved the structures of domains II and III, which stimulate arrested polymerase II elongation complexes in order to resume transcription. Domain I is conserved in evolution from yeast to human species and is homologous to the transcription factors elongin A and CRSP70. Domain I also interacts with the transcriptionally active RNA polymerase II holoenzyme and therefore, may have a function unrelated to the previously described transcription elongation activity of TFIIS. We have solved the structure of domain I of yeast TFIIS using NMR spectroscopy. Domain I is a compact four-helix bundle that is structurally independent of domains II and III of the TFIIS. Using the yeast structure as a template, we have modeled the homologous domains from elongin A and CRSP70 and identified a conserved positively charged patch on the surface of all three proteins, which may be involved in conserved functional interactions with the transcriptional machinery.
