Transcription research started from humble beginnings with the isolation of 3 distinct RNA polymerases. This was followed by a rich period of mapping promoters, enhancers and the isolation of the first sequence specific

The GTFs for pol II-mediated transcription include TFIIA, TFIIB, TFIID, TFIIE, TFIIF, and TFIIH. The transcr

Chromatin and Regulation of Gene Expressionmeters. The organization of this entity within the confines of a nucleus is an essential challenge for every eukaryotic cell. Darkly staining nuclear material was observed by early microscopists and called chromatin, which later proved to be the structural answer to this problem. Chromatin structure

STATs in Cytokine-mediated Transcriptional Regulationytokines and growth factors to regulate transcription. Upon stimulation, STATs become tyrosine phosphorylated to form functional dimers. Activated STAT dimers then translocate into the nucleus where they directly bind to the promoters of downstream genes to activate transcription. Posttranslational
