The requirements for preinitiation complex formation/stability and transcription by RNA polymerase II in yeast cells are different from those in vitro, thereby altering the current view of basal transcription.
Zfp106 functions as an RNA binding protein, binds directly to GGGGCC RNA repeats, is required in motor neurons to prevent ALS-like neurodegeneration in mice, and can suppress neurotoxicity in an established fly model of ALS.
Although the preinitiation complex for transcriptional initiation by RNA polymerase II contains highly conserved general transcription factors, there are kinetic and compositional differences in the initiation process among eukaryotic species.
Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.
Integrative structural biology reveals a novel complex comprising the TATA-box-binding protein, TBP, and two subunits, TAF11 and TAF13, of General Transcription Factor TFIID, suggesting a new regulatory state in TFIID function in RNA polymerase II transcription initiation.
