Perspective

Transcription Regulation Through Promoter-Proximal Pausing of RNA Polymerase II

Leighton J. Core and John T. Lis*

Recent work has shown that the RNA polymerase II enzyme pauses at a promoter-proximal site of many genes in Drosophila and mammals. This rate-limiting step occurs after recruitment and initiation of RNA polymerase II at a gene promoter. This stage in early elongation appears to be an important and broadly used target of gene regulation.
