Is sigma factor in eukaryotes
Witryna27 gru 2016 · Sigma factors (sigmas) are bacterial transcription factors that bind core RNA polymerase (RNAP) and direct transcription initiation at cognate promoter sites. … WitrynaFor bacterial RNA polymerase, only the sigma factor is needed for the enzyme to recognize the promoter. The eukaryotic transcription factors may indeed act as sigma factors to allow the eukaryoitic RNA polymerase to recognize the promoter. Some of the factors may be specific to certain promoters so groups of factors like these would be …

WitrynaThis compaction makes the gene promoter inaccessible without the assistance of other factors in the nucleus, and thus chromatin structure is a common site of regulation. Similar to the sigma factors in prokaryotes, the general transcription factors (GTFs) are a set of factors in eukaryotes that are required for all transcription events.
