crosstalk between ribosome biogenesis and transcription elongation

Posted on June 22, 2017June 23, 2017 by vicent

Our collaborators from Sebastian Chavez lab (Seville) have just published a new paper showing the crosstalk between ribosome biogenesis and transcription elongation. Glad to have contributed to this story. The ribosome assembly gene network is controlled by the feedback regulation of transcription elongation.

Using 5PSeq to unravel eIF5A dependent ribosome stalling

Posted on June 3, 2017June 23, 2017 by vicent

We have just published our first work 100% performed in our new lab at SciLifeLab-Karolinska Institutet. It has been a great collaboration with Dr. Paula Alepuz from the University of Valencia (Spain) eIF5A facilitates translation termination globally and promotes the elongation of many non polyproline-specific tripeptide sequences.

Protocol for genome-wide 5’RNA identification

Posted on February 7, 2016June 23, 2017 by vicent

We jut got published a new paper describing alternative methods for the genome-wide identification of 5’RNA ends. In this paper we do not only describe in detail our previous 5PSeq approach, but also new methods to identified alternative 5’RNA modifications. In particular we provide alternatives to use of the recently discontinued Tobacco Acid Pyrophosphatase. Genome-wide Read more about Protocol for genome-wide 5’RNA identification[…]
