How do bacteria avoid wasteful production of unnecessary proteins when their genes are always on? The answer lies in regulating the operon. As trp levels increase, trp binds to trpR, causing a ...
Peer pressure often evokes unexpected behavior, and protein partners might do the same. The Methyl-CpG binding protein 2 (MeCP2) has long been considered a transcriptional repressor, given its ...
A protein known to repress gene transcription at the molecular level in a variety of processes also blocks embryonic neural stem cells from differentiating into neurons, according to a new study. A ...
Researchers have developed two types of programmable repressor elements that can switch off the production of an output protein in synthetic biology circuits by up to 300-fold in response to almost ...
CRISPR interference (CRISPRi) is a novel method for specific gene knockdown. It's CRISPR, without the cut. The Horizon CRISPRi system uses a deactivated Cas9 nuclease (dCas9) fused to our proprietary ...
