Transcription elongation factor S-II

Gene

DST1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.

Miscellaneous

S-II binds to RNA-polymerase II in the absence of transcription.
Present with 6260 molecules/cell in log phase SD medium.1 Publication
