WebAug 23, 2024 · Protein (s) binds to distinct sites on the DNA, which activate, enhance or repress transcription. Despite being such an important process, very few tools exist to identify the proteins that interact with chromosome, most of which are in vitro in nature. WebTranscription factors are proteins that bind to DNA-regulatory sequences (enhancers and silencers), usually localized in the 5 -upstream region of target genes, to modulate the rate of gene transcription. This may result in increased or decreased gene transcription, protein synthesis, and subsequent altered cellular function. how many addresses are available in ipv6
