Sigma (σ) factors are general transcription factors that reversibly bind RNA polymerase (RNAP) and mediate transcription of all genes in bacteria. σ Factors play 3 major roles in the RNA synthesis initiation process: they (i) target RNAP holoenzyme to specific promoters, …
Web詳細. Importin beta-1 (also known as Importin subunit beta-1) facilitates nuclear protein import. This occurs either though association with a nuclear localization signal (NLS) and an adapter protein , such as an importin-alpha subunit, which which binds to nuclear, or directly where the protein acts as autonomous nuclear transport receptor. A sigma factor (σ factor or specificity factor) is a protein needed for initiation of transcription in bacteria. It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase (RNAP) to gene promoters. It is homologous to archaeal transcription factor B and to eukaryotic factor TFIIB. The … See more Different sigma factors are utilized under different environmental conditions.
