Gene expression depends on aonstant dialogue between nucleus, cytoplasm

Gene expression is the process by which genetic information is used to produce proteins, essential for cells to function properly. It takes place in two steps (first the transcription, then the translation), considered to be two independent processes until now. Today, microbiologists provide additional evidence that they are intrinsically related and that a protein complex called Ccr4-Not plays a key role in gene expression by acting as a messenger between the nucleus and the cytoplasm.
