Transcriptional regulation is all about getting RNA polymerase to the right place on the gene at the right time and making sure that it is competent to conduct transcription. Traditional views of this process place most of their emphasis on the events that precede initiation of transcription. We imagine a promoter-bound transcriptional activator (or collection of activators) recruiting componen...

We report on a young boy with neurodevelopmental disorder who is carrier of novel frameshift mutation in gene MAP7D3 (MAP7 domain containing 3) Xq26.3. The protein encoded by this belongs to the MAP7 (microtubuleassociated 7) family that proposed regulate kinesin-1 (KIF5B)-dependent intracellular transport, acting as Microtubule (MT)-tethered recruitment factors and activators kinesin [1-3]. An...

Genome-wide location analysis was used to determine how the yeast cell cycle gene expression program is regulated by each of the nine known cell cycle transcriptional activators. We found that cell cycle transcriptional activators that function during one stage of the cell cycle regulate transcriptional activators that function during the next stage. This serial regulation of transcriptional ac...

Recent work has shown that the combinatorial use of multiple TALE activators can selectively activate certain cellular genes in inaccessible chromatin regions. In this study, we aimed to interrogate the activation potential of TALEs upon transcriptionally silenced immune genes in the context of non-immune cells. We designed a unique strategy, in which a single TALE fused to the TATA-box binding...

Transcription initiation is a major regulatory step in eukaryotic gene expression. It involves the assembly of general transcription factors and RNA polymerase II into functional pre-initiation complex at core promoters. The degree chromatin compaction controls accessibility machinery to template DNA. Co-activators have critical roles this process by actively regulating accessibility. Many tran...

Cyclin dependent protein kinases (CDKs) play vital role in gene expression and cell cycle regulation. CDKs require cyclin binding activity, phosphorylation through CDK activating kinase (CAK), Cdc25, Wee 1 kinase. Non-cyclin CDK activators include CDK5 activators, Viral Cyclins and RINGO/Speedy. Among all CDK activators, CAK carries prime importance. The time frame of activating phosphorylation...

Efforts to increase the potency of transcriptional activators are generally unsuccessful because poor expression of activators in mammalian cells limits their delivery to target promoters. Here we report that the effectiveness of chimeric activators can be dramatically improved by expressing them as noncovalent tetrameric bundles. Bundled activation domains are much more effective at activating...
