1. Regulation of immunoglobulin transcription
Sammanfattning : Each Ig V-region has its own upstream promoter and the promoter of a mature Ig gene is thereby selected during the V(D)J recombination process. Upon comparison, it is evident that only one transcription factor binding site, the octamer, is preserved within all promoters. LÄS MER
2. The p97 ATPase and the Drosophila Proteasome : Protein Unfolding and Regulation
Sammanfattning : For all living systems, there is a requirement to recycle and regulate proteins. In eukaryotic organisms this is accomplished by the proteasome. The p97 ATPase is another highly conserved and essential complex present throughout the eukaryotic cell. LÄS MER
3. Regulation of gene expression in fruit flies : how does it start, and will it be remembered?
Sammanfattning : One of the most distinctive features of eukaryotic chromosomes is the bundling of DNA together with functionally associated RNA and proteins in chromatin. This allows huge amounts of DNA to be packed inside the very tiny space of the nucleus, and alterations in the structure of chromatin enable access to the DNA for transcription (“reading” genes by production of RNA copies).

4. Viral Strategies to Regulate Transcription and Pre-mRNA Splicing
Sammanfattning : A typical DNA virus encodes for a few key regulatory proteins that modify the host cell biosynthetic machinery to achieve a selective viral gene statement. One such example is illustrated by the adenovirus E4-ORF4 protein, which form an enzymatically active complex with the serine and threonine-specific protein phosphatase 2A (PP2A). LÄS MER
5. Transcription regulation across levels of chromatin organization
Sammanfattning : With advancements in high-throughput sequencing and high-resolution microscopy techniques, the significance of genome organization in transcription regulation is rapidly unveiling. Nonetheless, we are yet far from completely understanding this key relationship. LÄS MER
