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 ...

Origin-recognition complex, or ORC, plays an unexpectedly broad role in the regulation of human cell gene expression, according to a study in the journal Cell Reports. This is the first detailed study ...

A research team has identified the core gene expression networks regulated by key proteins that fundamentally drive phenomena such as cancer development, metastasis, tissue differentiation from stem ...
