Modulation of the DNA binding activity of transcription factors CREP, NFkappaB and HSF by H2O2 and TNF alpha. Differences between in vivo and in vitro effects.

abstract：:Human immunodeficiency virus type 1 (HIV-1) Rev is a small RNA-binding protein which is essential for viral replication. To investigate the structure of Rev we have mapped the binding sites of a panel of monoclonal antibodies (mAb) by protein footprinting and identified a mAb protecting amino acids within both the N- ...
