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 specific sigma factor used to initiate transcription of a given gene will vary, depending on the gene and on the environmental signals needed to initiate transcription of t… WebSep 8, 2024 · A plasmid platform according to the present invention comprises a nucleic acid sequence encoding a modified protein from which an intracellular domain, an extracellular domain, or a combination thereof of lysosome-associated membrane glycoprotein 2B (LAMP-2B) has been removed, and is based on the discovery that …
