Negative Elongation Factor NELF Represses Human Immunodeficiency Virus Transcription by Pausing the RNA Polymerase II Complex
19 Apr 2007
Abstract excerpt
Human immunodeficiency virus (HIV) transcription requires virally encoded Tat and the P-TEFb protein complex, which together associate with the Tat-activating region, a structured region in the nascent transcript. P-TEFb phosphorylates Proteins in the transcription elongation complex, including RNA polymerase II (pol II), to stimulate elongation and to overcome premature termination. However, the status of the...
