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

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. Limited proteolytic digestion showed that yeast TFIIS is composed of three structural domains, termed I, II, and III. The two C-terminal domains (II and III) are required for transcription activity. The structure of domain III has been solved previously by using NMR spectroscopy. Here, we report the NMR-derived structure of domain II: a three-helix bundle built around a hydrophobic core composed largely of three tyrosines protruding from one face of the C-terminal helix. The arrangement of known inactivating mutations of TFIIS suggests that two surfaces of domain II are critical for transcription activity.

Elongation factor TFIIS contains three structural domains: solution structure of domain II.,Morin PE, Awrey DE, Edwards AM, Arrowsmith CH Proc Natl Acad Sci U S A. 1996 Oct 1;93(20):10604-8. PMID:8855225^[1]
