transcription initiation
Ve showed earlier [101 that the region of the bla promoter of Tn3 protected by the RHA-polymerase (REAP), has the normal size (about 60bp) at RJAP/promoter molar ratio r(2, but rises to about twice this extent as r increases. Ve confirm here that the species corresponding to normal and extended footprint distinguish by their electrophoretic mobilities. Furtheraore, inspection of the complexes b...
متن کاملTranscriptional Coactivator CBP Facilitates Transcription Initiation and Reinitiation of HTLV-I and Cyclin D2 Promoter
HTLV-I is the etiologic agent for adult T-cell leukemia/lymphoma (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Taxi, the major activator of this virus, is a 40- kDa (353 amino acid) phosphoprotein, predominantly localized in the nucleus of the host cell, which functions to trans-activate both viral and cellular promoters. Recently it has been shown that HTLV-I a...

متن کاملViews of Transcription Initiation
Initiation of transcription is the first step in gene expression and a major point of regulation. Recent structural studies reveal the nature of the initiating complex and suggest new ways of accomplishing the processes required for initiation.
متن کاملEukaryotic transcription initiation
Transcription is defined as the synthesis of RNA from a DNA template. In bacteria, transcription of all genes is catalysed by a single RNA polymerase, whereas in the eukaryotic nucleus, three different RNA polymerases — Pol I, Pol II and Pol III — carry out the synthesis of different classes of RNA. Pol I and Pol III transcribe a limited number of genes encoding ribosomal RNAs, transfer RNAs an...
