Available in PDF, EPUB and Kindle. Book excerpt: The RNA exosome is a multi-subunit protein complex involved in RNA maturation, surveillance, and turnover of cellular RNA. It is composed of a nine subunit core that contains an RNA binding central channel and associates with the additional subunit Rrp44. Rrp44 contains a 3' to 5' processive exoribonuclease activity and an endoribonuclease activity in its N-terminal PIN domain. The exosome is present in both the nucleus and cytoplasm. In the nucleus, the exosome associates with a second nuclease, Rrp6, which is a distributive 3' to 5' exoribonuclease. Although a wealth of studies have helped to characterize the exosome, it is still not entirely clear how the exosome core functions in concert with these two nucleases to degrade RNA. In this dissertation, I present structural and biochemical studies of both the Rrp44 and Rrp6 bound exosome. In particular, I have attempted to crystallize a sub-complex of Rrp44 bound to the exosome, and present data that suggest that structured RNA can access Rrp44 without being first channeled through the exosome. Despite this conclusion, the exosome core still appears to down-regulate both the exonuclease and endonuclease activities of Rrp44, possibly by causing the protein to assume a conformation that prohibits it from promiscuous RNA degradation. Work on the Rrp6 containing exosme was conducted in attempts of obtaining an EM reconstruction of this complex. Crystallization of an RNA and Rrp6 binding exosome associated iii protein, Rrp47, was also attempted alone and in complex with Rrp6. Overall, the results that I present here will help to further characterize the function of the exosome in RNA mediated degradation. iv.

Available in PDF, EPUB and Kindle. Book excerpt: The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.

Download or read book Untranslated Gene Regions and Other Non coding Elements written by Lucy W. Barrett and published by Springer Science & Business Media. This book was released on 2013-06-26 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is now compelling evidence that the complexity of higher organisms correlates with the relative amount of non-coding RNA rather than the number of protein-coding genes. Previously dismissed as “junk DNA”, it is the non-coding regions of the genome that are responsible for regulation, facilitating complex temporal and spatial gene expression through the combinatorial effect of numerous mechanisms and interactions working together to fine-tune gene expression. The major regions involved in regulation of a particular gene are the 5’ and 3’ untranslated regions and introns. In addition, pervasive transcription of complex genomes produces a variety of non-coding transcripts that interact with these regions and contribute to regulation. This book discusses recent insights into the regulatory roles of the untranslated gene regions and non-coding RNAs in the control of complex gene expression, as well as the implications of this in terms of organism complexity and evolution.​
